Trial and errorTrial and error is a method for obtaining knowledge, both propositional knowledge and know-how. In trial and error, one tries an option to see if it works. If it works, then we have a solution. If it doesn't work - there is an error - then one tries another option.
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. In other versions, options are simply tried at random.
Bogosort can be viewed as a trial and error approach to sorting a list.
Trial and error has a number of features:
The scientific method can be regarded as containing an element of trial and error in its formulation and testing of hypotheses. Also compare genetic algorithms, simulated annealing and reinforcement learning - all varieties of search which apply the basic idea of trial and error.
