Assigning facilities to locations is one of the important problems, which significantly is influence in transportation cost reduction. In this study, we solve quadratic assignment problem (QAP), using a meta-heuristic algorithm with deterministic tasks and equality in facilities and location number. It should be noted that any facility must be assign to only one location. In this paper, first o...

Detecting community structure is crucial for uncovering the links between structures and functions in complex networks. Most of contemporary community detection algorithms employ single optimization criteria (e.g., modularity), which may have fundamental disadvantages. This paper considers the community detection process as a Multi-Objective optimization Problem (MOP). To solve the community de...

For constructing the best local codebook for image compression, there are many Vector Quantization (VQ) procedures, but simplest VQ procedure is Linde–Buzo–Gray (LBG) procedure. Techniques such as Gaussian Dissemination Function (GDF) used searching process in generating a global particle swarm optimization (PSO), Honeybee mating (HBMO), and Firefly (FA) procedures. However, when velocity very ...
