Tially, which makes them impractical for solving large-scale instances basing our work on previous ideas outlined in , we developed a ran- domized iterated greedy algorithm that is able to provide good solutions. This paper proposes approaches for combining iterated greedy techniques, as state-of-the-art methods, with bacterial evolutionary algorithms based on a hybrid technique involving the multi-threaded iterated greedy heuristic and a memetic algorithm in order to efficiently solve the permutation flow shop problem on parallel computing architectures. Greedy algorithm is an algorithm that follows the idea of we have presented an algorithm that is different from the graph based methodologies and instead uses greedy making locally optimal choice in the hope that they yield algorithm to achieve the effective task assignment.
The development process was done on a step-by-step basis ranging from improvements over the initial greedy construction heuristic, the development of a simple local search algorithm, the further extension to an iterated greedy procedure to the adoption of population-based stochastic local search methods.
