    "description": "<p>The capacitated p-median problem is a well-known location-allocation problem that is NP-hard. We proposed an advanced<br>\nGenetic Algorithm (GA) integrated with an Initial Solution Procedure for this problem to solve the medium and large-size<br>\ninstances. A 3<sup>3</sup> Full Factorial Design was performed where three levels were selected for the probability of mutation,<br>\npopulation size, and the number of iterations. Parameter tuning was performed to reach better performance at each<br>\ninstance. MANOVA and Post-Hoc tests were performed to identify significant parameter levels, considering both computational<br>\ntime and optimality gap percentage. Real data of Lorena and Senne (2003) and the data set presented by<br>\nStefanello et al. (2015) were used to test the proposed algorithm, and the results were compared with those of the other<br>\nheuristics existing in the literature. The proposed GA was able to reach the optimal solution for some of the instances in<br>\ncontrast to other metaheuristics and the Mat-heuristic, and it reached a solution better than the best known for the largest<br>\ninstance and found near-optimal solutions for the other cases. The results show that the proposed GA has the potential to<br>\nenhance the solutions for large-scale instances. Besides, it was also shown that the parameter tuning process might improve<br>\nthe solution quality in terms of the objective function and the CPU time of the proposed GA, but the magnitude of<br>\nimprovement may vary among different instances.</p>",
