This study incorporates the application of a linear programming technique for composition fish feed mixture to minimize cost without sacrificing nutrients levels. Designing best diet fry, fingerling, and growth stages is main goal this study. Regarding nutrient manufacturing costs, study's results show that variety elements can be combined much more effectively than in commercially available fe...

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...
