WebBest-first search algorithm visits next state based on heuristics function f(n) = h with lowest heuristic value (often called greedy). It doesn't consider cost of the path to that particular state. All it cares about is that which next state from the current state has lowest heuristics. WebAnswer (1 of 2): A greedy algorithm is called greedy because it takes the greediest bite at every step.

"WebOct 22, 2015 · If we consider beam search with just 1 beam will be similar to hill climbing or is there some other difference? As per definition of beam search, it keeps track of k best states in a hill-climbing algorithm.so if k = 1, we should have a regular hill climber. But i was asked the difference b/w them in a test so I am confused. " - Greedy best first search vs hill climbing
