Proposed by Hirsch, Pardalos, and Resende [23], C-GRASP is WebGreedy Randomized Adaptive Search Procedure (GRASP) is a recently ex-ploited method combining the power of greedy heuristics, randomisation, and local search[14]. It is a multi-start two-phase metaheuristic consisting of a “con-struction phase” and a “local search phase”. The construction phase is aimed at building an initial solution ...

A greedy algorithm is any algorithm that follows the problem-solving heuristic of making the locally optimal choice at each stage. In many problems, a greedy strategy does not produce an optimal solution, but a greedy heuristic can yield locally optimal solutions that approximate a globally optimal solution in a reasonable amount of time. Webpresent a greedy randomized adaptive search procedure (GRASP) for the job shop scheduling problem. Our interest in studying a new heuristic for a problem for which many e cient heuristics have been proposed is motivated by several observations. GRASP has been applied with success to a number of scheduling problems [4,5,12{14,17,18,26, 29,35,36,41].
