In computer science and mathematical optimization, a metaheuristic is a higher-level procedure or heuristic designed to find, generate, or select a heuristic (partial search algorithm) that may provide a sufficiently good solution to an optimization problem, especially with incomplete or imperfect information or limited computation capacity. In this algorithm, all sites are arranged as a directed tree such that the edges of the tree are assigned direction towards the site that holds the token. Here, a site is allowed to enter the Computer System if it possesses the token. Time stamp are related. Prerequisite – Mutual exclusion in distributed systems Raymond’s tree based algorithm is lock based algorithm for mutual exclusion in a distributed system in which a site is allowed to enter the critical section if it has the token. Also called as simply a heuristic. M Metaheuristics (3 C, 13 P) Pages in category "Heuristic algorithms" The following 16 pages are in this category, out of 16 total.
