Question

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

please select the best answer from the choices provided

Explanation:

• Option A: Hill climbing is a heuristic that moves towards better solutions, not all alternatives.
• Option B: An algorithm is a step - by - step procedure, not necessarily checking all alternatives (some algorithms are efficient and don't check all).
• Option C: Trial and error involves trying every possible alternative, which can be very time - consuming as it has to go through each option.
• Option D: Working backwards starts from the goal and works towards the start, not checking all alternatives.

Answer:

C. trial and error
