Using linear programs, we give the necessary and sufficient conditions for the solvability of a fuzzy LR algebraic linear system. Fuzzy LR algebraic linear systems are linear systems with LR fuzzy coefficient matrix and ...

Here, we propose a hybrid metaheuristic algorithm based on genetic

algorithm and variable neighborhood search for solving uncapacitated

facility location problem which is one of the most important problem in ...

Problems of global optimization naturally arise in many applications.

We present two new metaheuristic algorithms that are hybridization of

genetic algorithm and variable neighborhood search for finding a ...
