In      mathematics and      computer science,      algorithm is      self-contained sequence of      actions to be performed.      Algorithms perform      calculation,      data processing, and/or      automated reasoning tasks.

     algorithm is      effective method that can be expressed within      finite amount of      space and time [1] and in      well-defined formal language [2] for calculating      function.[3] Starting from      initial state and      initial input (perhaps empty), [4]      instructions describe      computation that, when executed, proceeds through      finite [5] number of well-defined successive states, eventually producing      "output"[6] and terminating at      final ending state.      transition from one state to      next is not necessarily deterministic; some algorithms, known as      randomized algorithms, incorporate      random input [7].

     concept of      algorithm has existed for centuries; however,      partial formalization of what would become      modern algorithm began with      attempts to solve      Entscheidungsproblem (the "decision problem") posed by David Hilbert in      1928.
