I am trying to solve a quadratic MIP objective function with cplex, but it requires a long computation time. I tried to change some Cplex options but in useless.

Could someone tell me what would be best to try. You find attached my log and model files 

Thank you.

What sort of modeling language is this .mod file? It does not seem to be OPL. Maybe you can export the problem as a SAV file and attach that instead?

Also, your log file contains the output for many solves. Which is the output for the solve that takes too long?
