We propose a new optimization model to detect overlapping communities in networks. The elaborates suggestions contained Zhang et al. (2007), which were identified through the use of fuzzy membership function, calculated as outcome mathematical programming problem. In our approach, we retain idea using both and communities, but replace objective function proposed there with another one, based on...

one of the main principles of the passive defense is the principle of site selection. in this paper, we propose a multiple objective nonlinear programming model that considers the principle of the site selection in terms of two qualitative and quantitative aspects. the purpose of the proposed model is selection of the place of key production facilities of a system in which not only it observes ...

There are various automatic programming models inspired by evolutionary computation techniques. Due to the importance of devising an automatic mechanism to explore the complicated search space of mathematical problems where numerical methods fails, evolutionary computations are widely studied and applied to solve real world problems. One of the famous algorithm in optimization problem is shuffl...
