Uniform-cost Search Algorithm: Uniform-cost search is a searching algorithm used for traversing a weighted tree or graph. This algorithm comes into play when a different cost is available for each edge. The primary goal of the uniform-cost search is to find a path to the goal node which has the lowest cumulative cost.

WebDec 4, 2011 · BFS is an instance of tree search and graph search algorithms in which a node is selected for expansion based on the evaluation function f(n) = g(n) + h(n), where g(n) is length of the path from the root to n and h(n) is an estimate of the length of the path from n to the goal node. In a BFS algorithm, the node with the lowest evaluation (i.e. … WebMar 27, 2024 · Which heuristic function is used in Best-First Search? So the major difference between Best-First Search (informed) and Uniform-Cost Search (uninformed) is that in BFS, we use a heuristic function to determine which node to go next. In UCS, we always take the lowest cost that is calculated from my initial state.
