Esneyder is a Computer Science Engineer who holds a master’s degree in Industrial Engineering. He has a strong knowledge of statistical and analytical tools. He has been programming metaheuristics and creating mathematical models for 10 years, in GAMS, AMPL, Python, and directly in Excel (using the basic solver and also, the OpenSolver for big problems). He knows about linear and nonlinear theory. Likewise, he knows how to deal with NP-Hard problems when you cannot get a solution in a polynomial time due to the exponential efforts required insofar as the problem instance increase. Specifically, he has implemented genetic algorithms, simulated annealing, tabu search, ant colony, 2-opt algorithm, pilot method, etc.
