[Topic to discuss GA and CPLEX]
I've seen some papers trying to integrate genetic algorithm with CPLEX, such as here and here. Although they integrated both, it is done in 2 different steps; that means, they use CPLEX in one step and the results obtained are used as input for the second step, in which GA is used (or vice-versa).
However, I am wondering if it would be possible to integrate CPLEX in GA on the same step to solve large instances of problems. Considering the GA methodology and the fact that CPLEX is a solver, initially, I would say no to this question. But I would like to open this discussion about the integration of heuristic methods with CPLEX to know other opinions and perspectives.
If someone already worked with both, heuristic and CPLEX integrated, and can share some tips, I would be really grateful.
