WebDec 15, 2012 · Uniform Cost Search as it sounds searches in branches which are more or less the same in cost. Uniform Cost Search again demands the use of a priority queue. Recall that Depth First Search used a priority queue with the depth upto a particular node being the priority and the path from the root to the node being the element stored.

What is the difference between Greedy-Search and Uniform-Cost-Search?

WebSEARCH (or GRAPH-SEARCH) –where a search strategy is defined by picking the order of node expansion. • With best-first, node is selected for expansion based on evaluation function f(n). • Evaluation function is a cost estimate; expand lowest cost node first (same as uniform-cost search but we replace g with f). WebJan 24, 2024 · 1. The Greedy algorithm follows the path B -> C -> D -> H -> G which has the cost of 18, and the heuristic algorithm follows the path B -> E -> F -> H -> G which has the cost 25.
