Definitions of anytime algorithm

  1. An algorithm that returns a sequence ofapproximations to the correct answer such that eachapproximation is no worse than the previous one, i.e. thealgorithm can be stopped at _any time_.Newton-Raphson iteration applied to finding the squareroot of a number b is another example:x = (x + b / x) / 2Each new x is closer to the square root than the previous one.Applications might include a real-time control system or achess program that is allowed a fixed thinking time. foldoc_fs
