WebI'm trying to use the Simple hill climbing algorithm to solve the travelling salesman problem. I want to create a Java program to do this. I know it's not the best one to use but I mainly want it to see the results and then compare the results with the following that I will also create: Stochastic Hill Climber; Random Restart Hill Climber WebHill climbing is a mathematical optimization algorithm, which means its purpose is to find the best solution to a problem which has a (large) number of possible solutions. Explaining the algorithm (and optimization in general) is best done using an example.
