Algorithm

From AoPSWiki

An algorithm is a mathematical rule or procedure for solving a problem that is applied in other sciences like Computer Science, where it plays a very significant role. Algorithms can be implemeted as pseudocode, flowcharts or written text. The running time of an algorithm describes the time it needs to run in a polynomial form. Thus, there are P and NP problems. An NP problem does not have a standard solution, contrary to P problems.
