In Permutation Flow-shop Scheduling problems solving, Genetic Algorithm (GA) had been regarded as a meta-heuristic for approximation in combinatorial optimization. However, the standard Genetic Algorithm has suffered from slow convergence and trapped into local optimum when meeting the problems with higher complexities. In this research, we introduce a new heuristic by using the concept of Ant Colony Optimization (ACO) to extract patterns from the chromosomes generated in previous generations. The proposed heuristic is composed of two phases: 1. the blocks mining phase using ACO approach to establish a set of non-overlap block archive and the rest of cities in set...
