Greedy randomized heuristic
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 ... WebMar 30, 2024 · Our heuristic algorithm is able to generate better results in comparison with existing heuristics. Greedy Randomized Adaptive Search Procedure (GRASP) and Simulated Annealing (SA) are exploited to obtain better solutions for RBPP. A new construction method based on cliques and zigzag sorting are built for GRASP and SA.
