WebJul 4, 2024 · Hill climbing (HC) is a general search strategy (so it's also not just an algorithm!). HC algorithms are greedy local search algorithms, i.e. they typically only find local optima (as opposed to global optima) and they do that greedily (i.e. they do not look ahead). The idea behind HC algorithms is that of moving (or climbing) in the direction ... WebMar 4, 2024 · Hill climbing is a mathematical optimization technique which belongs to the family of local search.
