Which problem solving strategy looks at every possible alternative and could take a very long time?

A.

hill climbing

B.

algorithm

C.

trial and error

D.

working backwards

The correct answer for this question is this one: "C. trial and error"

The problem solving strategy that looks at every possible alternative and could take a very long time is called

A. hill climbing

B. algorithm

C. trial and error

D. working backwards

Trial and error. This problem solving strategy is the least efficient compared to the other strategies (hill climbing, algorithm, and working backwards). From the name "trial", in solving a problem, you try every possible solution until you reach the correct solution. This may take a while especially when a problem has several possible solutions.
