Every theoretical problem asks for an answer or solution. Trying to find a solution to a problem is known as problem solving. That is, a problem is a gap between an actual and [[Desire|desired]] situation. The [[time]] it takes to solve a problem is a way of [[Measure|measuring]] [[complexity]].[1] Many problems have no [[discovered]] solution and are therefore classified as an open problem. | Every theoretical problem asks for an answer or solution.
