-By default GAMS/CPLEX calculates marginals for a model with a quadratic objective and linear constraints. Furthermore,​ GAMS/CPLEXD calculates marginals for a model with a quadratic objective and quadratic constraints. ​ Sometimes some presolve reductions prevents the calculation of marginals. To turn off those presolve reductions and enable the calculation of marginals you can use the following option: "secret 1136 i 2", for example, in the following way:+By default GAMS/CPLEX calculates marginals for a model with a quadratic objective and linear constraints.
