Greedy randomized heuristic

WebOct 1, 2024 · The solutions obtained by the multi-start greedy randomized heuristic (MSH), described in Section 4, were provided as initial feasible solutions for each execution of all the formulations. We defined a time limit of 30 s as the stopping criterion for obtaining an initial feasible solution with the heuristic MSH. Webby Martins et al. [30]. The construction phase of their hybrid heuristic for the Steiner problem in graphs follows the greedy randomized strategy of GRASP, while the local search phase makes use of two different neighborhood structures as a VND strategy. Theirheuristic was later improvedbyRibeiro, Uchoa, andWerneck [39], oneof the key
