Problem-solving strategies which don't guarantee solutions, but make efficient use of time is Heuristics.
Any problem-solving strategy that employs a practical approach or numerous short cuts in order to provide answers that might not be ideal but are adequate given a constrained timeline or deadline is known as a heuristic, or heuristic technique.
