WebAxiom 2 ― The probability that at least one of the elementary events in the entire sample space will occur is 1, i.e: WebThe objective is to find a path that minimizes the cost. Backtracking search Backtracking search is a naive recursive algorithm that tries all possibilities to find the minimum cost path. Here, action costs can be either positive or negative. Breadth-first search (BFS) Breadth-first search is a graph search algorithm that does a level-by-level traversal.
