“…An Extremal Optimization (EO) procedure, an evolutionary algorithm which progressively eliminates the least fit solutions, is hybridized with RoTS and run in parallel (ParEOTS) by Munera et al [80]. Improvements were achived when RoTS, EO and a GA run in parallel using a framework designed for cooperative parallel local searches (CPLS-GA) in López et al [63]. While the CPLS framework is designed to handle single-solution metaheuristics, another framework was proposed to ease the implementation of hybrid metaheuristics using cooperative parallelism, called Parallel Hybridization of Simple Heuristics (PHYSH) in López et al [64].…”
