In some search problems, we may be interested in finding a feasible solution to the problem, without necessarily attempting to optimise this solution.

In some search problems, the main goal is to find a solution that works or meets the basic requirements, rather than finding the best or optimal solution. This is often the case when the optimal solution is too complex or time-consuming to find. In these cases, a feasible solution can be found more quickly and can be good enough for the purposes of the problem. This approach can be useful in situations where a quick solution is needed, or where the optimal solution is not significantly better than a feasible solution.
