Heuristic

In computer science, a method of investigation based on the progressive approximation of a problem is called a heuristic.

I don't think that heuristic will work.

It's a heuristic solution.

Tom's approach to navigating corn mazes is heuristic.

"The heuristic appraisal is the 'identification and evaluation of hints and clues that can provide direction to inquiry in the sometimes large gap between the extremes of complete knowledge and complete ignorance'”.

If a heuristic algorithm works for most of the input data or its maximum percentage error is tolerable, we may prefer the heuristic algorithm to an optimum algorithm that requires a long time.
