Hill climbing is a simple optimization algorithm used in Artificial Intelligence (AI) to find the best possible solution for a given problem. It belongs to the family of local search algorithms and is often used in optimization problems where the goal is to find the best solution from a set of possible solutions.
- In Hill Climbing, the algorithm starts with an initial solution and then iteratively makes small changes to it in order to improve the solution. These changes are based on a heuristic function that evaluates the quality of the solution. The algorithm continues to make these small changes until it reaches a local maximum, meaning that no further improvement can be made with the current set of moves.
- There are several variations of Hill Climbing, including steepest ascent Hill Climbing, first-choice Hill Climbing, and simulated annealing. In steepest ascent Hill Climbing, the algorithm evaluates all the possible moves from the current solution and selects the one that leads to the best improvement. In first-choice Hill Climbing, the algorithm randomly selects a move and accepts it if it leads to an improvement, regardless of whether it is the best move. Simulated annealing is a probabilistic variation of Hill Climbing that allows the algorithm to occasionally accept worse moves in order to avoid getting stuck in local maxima.
Hill Climbing can be useful in a variety of optimization problems, such as scheduling, route planning, and resource allocation. However, it has some limitations, such as the tendency to get stuck in local maxima and the lack of diversity in the search space. Therefore, it is often combined with other optimization techniques, such as genetic algorithms or simulated annealing, to overcome these limitations and improve the search results.
Advantages of Hill Climbing algorithm:
- Hill Climbing is a simple and intuitive algorithm that is easy to understand and implement.
- It can be used in a wide variety of optimization problems, including those with a large search space and complex constraints.
- Hill Climbing is often very efficient in finding local optima, making it a good choice for problems where a good solution is needed quickly.
- The algorithm can be easily modified and extended to include additional heuristics or constraints.
Disadvantages of Hill Climbing algorithm:
- Hill Climbing can get stuck in local optima, meaning that it may not find the global optimum of the problem.
- The algorithm is sensitive to the choice of initial solution, and a poor initial solution may result in a poor final solution.
- Hill Climbing does not explore the search space very thoroughly, which can limit its ability to find better solutions.
- It may be less effective than other optimization algorithms, such as genetic algorithms or simulated annealing, for certain types of problems.
Hill Climbing is a heuristic search used for mathematical optimization problems in the field of Artificial Intelligence. Given a large set of inputs and a good heuristic function, it tries to find a sufficiently good solution to the problem. This solution may not be the global optimal maximum.
- In the above definition, mathematical optimization problems imply that hill-climbing solves the problems where we need to maximize or minimize a given real function by choosing values from the given inputs. Example- Travelling salesman problem where we need to minimize the distance traveled by the salesman.
- ‘Heuristic search’ means that this search algorithm may not find the optimal solution to the problem. However, it will give a good solution in a reasonable time.
- A heuristic function is a function that will rank all the possible alternatives at any branching step in the search algorithm based on the available information. It helps the algorithm to select the best route out of possible routes.
Features of Hill Climbing
1. variant of generating and test algorithm: .
It is a variant of generating and testing algorithms. The generate and test algorithm is as follows :
- Generate possible solutions.
- Test to see if this is the expected solution.
- If the solution has been found quit else go to step 1.
Hence we call Hill climbing a variant of generating and test algorithm as it takes the feedback from the test procedure. Then this feedback is utilized by the generator in deciding the next move in the search space.
2. Uses the Greedy approach :
At any point in state space, the search moves in that direction only which optimizes the cost of function with the hope of finding the optimal solution at the end.
Types of Hill Climbing
1. simple hill climbing:.
It examines the neighboring nodes one by one and selects the first neighboring node which optimizes the current cost as the next node.
Algorithm for Simple Hill climbing :
- Evaluate the initial state. If it is a goal state then stop and return success. Otherwise, make the initial state as the current state.
- Select a state that has not been yet applied to the current state and apply it to produce a new state.
- If the current state is a goal state, then stop and return success.
- If it is better than the current state, then make it the current state and proceed further.
- If it is not better than the current state, then continue in the loop until a solution is found.
- Exit from the function.
2. Steepest-Ascent Hill climbing:
It first examines all the neighboring nodes and then selects the node closest to the solution state as of the next node.
Algorithm for Steepest Ascent Hill climbing :
- Select a state that has not been yet applied to the current state.
- Initialize a new ‘best state’ equal to the current state and apply it to produce a new state.
- If the current state is a goal state, then stop and return success.
- If it is better than the best state, then make it the best state else continue the loop with another new state.
- Make the best state as the current state and go to Step 2 of the second point.
3. Stochastic hill climbing:
It does not examine all the neighboring nodes before deciding which node to select. It just selects a neighboring node at random and decides (based on the amount of improvement in that neighbor) whether to move to that neighbor or to examine another.
- Evaluate the initial state. If it is a goal state then stop and return success. Otherwise, make the initial state the current state.
- Apply the successor function to the current state and generate all the neighbor states.
- Among the generated neighbor states which are better than the current state choose a state randomly (or based on some probability function).
- If the chosen state is the goal state, then return success, else make it the current state and repeat step 2 of the second point.
State Space diagram for Hill Climbing
The state-space diagram is a graphical representation of the set of states our search algorithm can reach vs the value of our objective function(the function which we wish to maximize).
- X-axis: denotes the state space ie states or configuration our algorithm may reach.
- Y-axis: denotes the values of objective function corresponding to a particular state.
The best solution will be a state space where the objective function has a maximum value(global maximum).
Different regions in the State Space Diagram:
- Local maximum: It is a state which is better than its neighboring state however there exists a state which is better than it(global maximum). This state is better because here the value of the objective function is higher than its neighbors.
- Global maximum: It is the best possible state in the state space diagram. This is because, at this stage, the objective function has the highest value.
- Plateau/flat local maximum: It is a flat region of state space where neighboring states have the same value.
- Ridge: It is a region that is higher than its neighbors but itself has a slope. It is a special kind of local maximum.
- Current state: The region of the state space diagram where we are currently present during the search.
- Shoulder: It is a plateau that has an uphill edge.
Problems in different regions in Hill climbing
Hill climbing cannot reach the optimal/best state(global maximum) if it enters any of the following regions :
- Local maximum: At a local maximum all neighboring states have a value that is worse than the current state. Since hill-climbing uses a greedy approach, it will not move to the worse state and terminate itself. The process will end even though a better solution may exist. To overcome the local maximum problem: Utilize the backtracking technique . Maintain a list of visited states. If the search reaches an undesirable state, it can backtrack to the previous configuration and explore a new path.
- Plateau: On the plateau, all neighbors have the same value. Hence, it is not possible to select the best direction. To overcome plateaus: Make a big jump. Randomly select a state far away from the current state. Chances are that we will land in a non-plateau region.
- Ridge: Any point on a ridge can look like a peak because movement in all possible directions is downward. Hence the algorithm stops when it reaches this state. To overcome Ridge: In this kind of obstacle, use two or more rules before testing. It implies moving in several directions at once.
Here is a simple example of hill climbing in Python:

Convergent thinking problems are those problems that have known solutions that can be reached by narrowing down the possible answers, whereas divergent thiking problems have many possible solutions. Some solutions work; some do not.
An algorithm is a prescribed method of problem solving that guarantees a correct solution if the method suits the problem and if it is carried out properly. Solving a mathematical problem by use of a formula is an example of the use of an algorithm.
Insight solutions or Eureka insights occur when a sudden solution comes to mind - that "a-ha" idea.
Thinking-outside-the-box occurs when a person does not follow strict self-imposed constraints and looks at a problem differently.
Heuristics are rules of thumb that help to simplify and solve problems, though they do not guarantee a correct solution. Many types of heuristics are in use. We use the representative heuristic to estimate the probability of one event based on how typical it is of another event. We use the availability heuristic to make decisions based on the ease with which estimates come to mind or how available they are to our awareness.
Problem representation, defining or interpreting the problem, is the first step in problem solving. We decide what the problem is and what steps we are going to use to solve the problem. Expertise in a field increases a person's ability to interpret a particular problem.
Trial and error is a problem-solving strategy based on the successive elimination of incorrect solutions until the correct one is found. But trial and error is time-consuming, and a hit-or-miss approach.
Hill climbing is a heuristic in which each step moves the problem solver closer to the final goal.
Another heuristic is the creation of sub goals-intermediate, more manageable goals that may make it easier to reach the final goal.
Means-end analysis, a heuristic that combines hill climbing and sub goals, aims to reduce the discrepancy between the current situation and the desired goal at a number of intermediate points.
Working backward involves working from the desired goal back to the given conditions.

Understanding Hill Climbing Algorithm in Artificial Intelligence
December 16, 2020.
A hill-climbing algorithm is an Artificial Intelligence (AI) algorithm that increases in value continuously until it achieves a peak solution. This algorithm is used to optimize mathematical problems and in other real-life applications like marketing and job scheduling.
This article will improve our understanding of hill climbing in artificial intelligence. It discusses various aspects such as features, problems, types, and algorithm steps of the hill-climbing algorithm. The article will also highlight the applications of this algorithm.
Introduction to hill climbing algorithm
A hill-climbing algorithm is a local search algorithm that moves continuously upward (increasing) until the best solution is attained. This algorithm comes to an end when the peak is reached.
This algorithm has a node that comprises two parts: state and value. It begins with a non-optimal state (the hill’s base) and upgrades this state until a certain precondition is met. The heuristic function is used as the basis for this precondition. The process of continuous improvement of the current state of iteration can be termed as climbing. This explains why the algorithm is termed as a hill-climbing algorithm .
A hill-climbing algorithm’s objective is to attain an optimal state that is an upgrade of the existing state. When the current state is improved, the algorithm will perform further incremental changes to the improved state. This process will continue until a peak solution is achieved. The peak state cannot undergo further improvements.
Features of a hill climbing algorithm
A hill-climbing algorithm has four main features:
- It employs a greedy approach: This means that it moves in a direction in which the cost function is optimized. The greedy approach enables the algorithm to establish local maxima or minima.
- No Backtracking: A hill-climbing algorithm only works on the current state and succeeding states (future). It does not look at the previous states.
- Feedback mechanism: The algorithm has a feedback mechanism that helps it decide on the direction of movement (whether up or down the hill). The feedback mechanism is enhanced through the generate-and-test technique .
- Incremental change: The algorithm improves the current solution by incremental changes.
State-space diagram analysis
A state-space diagram provides a graphical representation of states and the optimization function. If the objective function is the y-axis, we aim to establish the local maximum and global maximum.
If the cost function represents this axis, we aim to establish the local minimum and global minimum. More information about local minimum, local maximum, global minimum, and global maximum can be found here .
The following diagram shows a simple state-space diagram. The objective function has been shown on the y-axis, while the state-space represents the x-axis.

A state-space diagram consists of various regions that can be explained as follows;
- Local maximum: A local maximum is a solution that surpasses other neighboring solutions or states but is not the best possible solution.
- Global maximum: This is the best possible solution achieved by the algorithm.
- Current state: This is the existing or present state.
- Flat local maximum: This is a flat region where the neighboring solutions attain the same value.
- Shoulder: This is a plateau whose edge is stretching upwards.
Problems with hill climbing
There are three regions in which a hill-climbing algorithm cannot attain a global maximum or the optimal solution: local maximum, ridge, and plateau.
At this point, the neighboring states have lower values than the current state. The greedy approach feature will not move the algorithm to a worse off state. This will lead to the hill-climbing process’s termination, even though this is not the best possible solution.
This problem can be solved using momentum. This technique adds a certain proportion (m) of the initial weight to the current one. m is a value between 0 and 1. Momentum enables the hill-climbing algorithm to take huge steps that will make it move past the local maximum.
In this region, the values attained by the neighboring states are the same. This makes it difficult for the algorithm to choose the best direction.
This challenge can be overcome by taking a huge jump that will lead you to a non-plateau space.
Image Source: Tutorial and Example
The hill-climbing algorithm may terminate itself when it reaches a ridge. This is because the peak of the ridge is followed by downward movement rather than upward movement.
This impediment can be solved by going in different directions at once.

Types of hill climbing algorithms
The following are the types of a hill-climbing algorithm:
Simple hill climbing
This is a simple form of hill climbing that evaluates the neighboring solutions. If the next neighbor state has a higher value than the current state, the algorithm will move. The neighboring state will then be set as the current one.
This algorithm consumes less time and requires little computational power. However, the solutions produced by the algorithm are sub-optimal. In some cases, an optimal solution may not be guaranteed.
- Conduct an assessment of the current state. Stop the process and indicate success if it is a goal state.
- Perform looping on the current state if the assessment in step 1 did not establish a goal state.
- Continue looping to attain a new solution.
- Assess the new solution. If the new state has a higher value than the current state in steps 1 and 2, then mark it as a current state.
- Continue steps 1 to 4 until a goal state is attained. If this is the case, then exit the process.
Steepest – Ascent hill climbing
This algorithm is more advanced than the simple hill-climbing algorithm. It chooses the next node by assessing the neighboring nodes. The algorithm moves to the node that is closest to the optimal or goal state.
- Establish or set a state (X) such that current state successors have higher values than it.
- Run the new operator and produce a new solution.
- Assess this solution to establish whether it is a goal state. If this is the case, exit the program. Otherwise, compare it with the state (X).
- If the new state has a higher value than the state (X), set it as X. The current state should be set to Target if the state (X) has a higher value than the current state.
Stochastic hill climbing
In this algorithm, the neighboring nodes are selected randomly. The selected node is assessed to establish the level of improvement. The algorithm will move to this neighboring node if it has a higher value than the current state.
Applications of hill climbing algorithm
The hill-climbing algorithm can be applied in the following areas:
A hill-climbing algorithm can help a marketing manager to develop the best marketing plans. This algorithm is widely used in solving Traveling-Salesman problems. It can help by optimizing the distance covered and improving the travel time of sales team members. The algorithm helps establish the local minima efficiently.
Hill climbing is useful in the effective operation of robotics. It enhances the coordination of different systems and components in robots.
The hill climbing algorithm has also been applied in job scheduling. This is a process in which system resources are allocated to different tasks within a computer system. Job scheduling is achieved through the migration of jobs from one node to a neighboring node. A hill-climbing technique helps establish the right migration route.
Hill climbing is a very resourceful technique used in solving huge computational problems. It can help establish the best solution for problems. This technique has the potential of revolutionizing optimization within artificial intelligence.
In the future, technological advancement to the hill climbing technique will solve diverse and unique optimization problems with better advanced features.
