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 ... reading laterally definitionWebUsing the hill climbing algorithm, we can start to improve the locations that we assigned to the hospitals in our example.
