Greedy randomized heuristic

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].

A Greedy Randomised Search Heuristic for Time-Constrained …

The greedy randomized adaptive search procedure (also known as GRASP) is a metaheuristic algorithm commonly applied to combinatorial optimization problems. GRASP typically consists of iterations made up from successive constructions of a greedy randomized solution and subsequent iterative improvements of it through a local search. The greedy randomized solutions are generated by adding elements to the problem's solution set from a list of elements ranked by a …
