Which uninformed search strategy is NOT complete when the search space has infinite depth?
Which uninformed search strategy is NOT complete when the search space has infinite depth?
a)
Breadth-first searchb)
Depth-first searchc)
Iterative deepening searchd)
Uniform-cost search with positive step costsExplanation
