This paper proposes a GA-based reduced search space technique (GA-RSS) for the optimal design of steel moment frames. It tries to reduce the computation time by focusing the search around the boundaries of the constraints, using a ranking-based constraint handling to enhance the efficiency of the algorithm. This attempt to reduce the search space is due to the fact that in most optimization pro...

One of the approaches to improve operation indices, such as power loss and reliability, is smoothen voltage profiles. Energy management generation units network reconfiguration are two methods achieve this. Hence, latter presented in this paper a distribution with distributed units. To end, an objective function formulated aiming minimize enhance operating situation network. This problem subjec...

In this paper, for topology optimization of double layer grids, an efficient optimization method is presented by combination of Imperialist Competitive Algorithm (ICA) and Gravitational Search Algorithm (GSA) which is called ICA-GSA method. The present hybrid method is based on ICA but the moving of countries toward their relevant imperialist is done using the la...

College students are the group with most entrepreneurial vitality and potential. How to cultivate their innovative ability is one of important urgent issues facing this current social development. This paper proposes a reliable, intelligent prediction model intentions, providing theoretical support for guiding college students’ positive intentions. The mainly uses improved crow search algorithm...

This paper presents a novel metaheuristic optimization algorithm inspired by the geometrical features of circles, called circle search (CSA). The is most well-known geometric object, with various including diameter, center, perimeter, and tangent lines. ratio between radius line segment orthogonal function angle opposite to radius. plays an important role in exploration exploitation behavior CS...

To effectively solve the permutation flow-shop scheduling problem (PFSP), an adaptive dynamic neighborhood crow search algorithm (AdnCSA) is proposed to minimize makespan. Firstly, a modified heuristic based on nawaz-enscore-ham (NEH) was improve quality and diversity of initial population. Secondly, smallest-position-value (SPV) rule used encode population so that it can handle discrete proble...

economic dispatch with valve point effect and prohibited operating zones (pozs) is a non-convex and discontinuous optimization problem. harmony search (hs) is one of the recently presented meta-heuristic algorithms for solving optimization problems, which has different variants. the performances of these variants are severely affected by selection of different parameters of the algorithm. intel...
