Types of Hill Climbing Algorithms There are three main types of hill climbing algorithms, each with its own way of searching for the best solution: 1. Simple hill climbing Simple hill climbing is like taking the first good step you find. In this version: The algorithm looks at nearby solutio...
Add a new constructor parameterrandom_deterministicthat tells the framework to use an random number generator seeded from the rank-0 random number generator for each individual evaluated. This allows use of random numbers during hillclimbing or evaluation but still produces random numbers that are repr...

number of moves from the start to the goal. For simplicity, we will limit our attention to these. Using breadth-first search, or some other suitable graph algorithm, compute the minimum distance (depth = number of moves) to each cell from the start cell. Create an objective function ...

a) For each function, apply hill climbing, starting from 100 random points in the range. Repeat this procedure for each choice of step size in [0.01, 0.05, 0.1, 0.2]. What patterns do you see? b) Repeat using local beam search with beam width in [2, 4, 8, 16], performing 100 ...
