  Trial and error - Wikipedia, the free encyclopedia
Trial and error (also known in computer science literature as generate and test and as "guess and check" when solving equations in elementary algebra) is a method of problem solving for obtaining knowledge, both propositional knowledge and know-how.
In trial and error, one selects (or generates) a possible answer, applies it to the problem and, if it is not successful, selects (or generates) another possibility that is subsequently tried.
In some versions of trial and error, the option that is a priori viewed as the most likely one should be tried first, followed by the next most likely, and so on until a solution is found, or all the options are exhausted.
