this article proposes a new algorithm for finding a good approximate set of non-dominated solutions for solving generalized traveling salesman problem. Random gravitational emulation search algorithm (RGES (is presented for solving traveling salesman problem. The algorithm based on random search concepts, and uses two parameters, speed and force of gravity in physics. The proposed algorithm is ...

the present research simulates time-periodic unsteady transonic flow around pitching airfoils via the solution of unsteady euler and navier-stokes equations, using time spectral method (tsm) and compares it with the traditional methods such as bdf and explicit structured adaptive grid method. the tsm uses a fourier representation in time and hence solves for the periodic state directly accordin...

in this study, we discuss the capacitated facility location-allocation problem with uncertain parameters in which the uncertainty is characterized by given finite numbers of scenarios. in this model, the objective function minimizes the total expected costs of transportation and opening facilities subject to the robustness constraint. to tackle the problem efficiently and effectively, an effici...

Abstract Action recognition based on video surveillance becomes possible because of the rapid development action recognition, temporal and spatial-temporal technology. A video-based behavior detection algorithm designed to find information interest from videos. In process detection, feature extraction is often carried out space time dimensions. However, calculation amount videos sent into deep ...

Wireless Sensor Network WSN deployment is an active research area. Its goal to deploy sensors in certain environment efficiently optimize some evaluation measures. Meta heuristic searching optimization approaches have been proven be effective solving problem. They strong power exploring the solution space and converging toward theoptimal region. One key factor achieving more meta-heuristic sele...

introduction:  breast  cancer  is  a  leading  cause  of  death  among  females  throughout  the  world.  currently,  radiologists are able to detect only 75% of breast cancer cases. making use of computer-aided design (cad)  can play an important role in helping radiologists perform more accurate diagnoses.   material and methods: using our hybrid method, the background and the pectoral muscle...
