I want to get an optimality gap like a getMIPRelativeGap function in cplex 11.2.
I am using cplex 11.1.
Or, How can I calculate optimality gap?

I am sorry not to write a question well by English.

With CPLEX 11.1, you could use something like the following to calculate the relative MIPGAP:

double relativeGap = abs(cplex.getObjValue()-cplex.getBestObjValue())/(abs(cplex.getObjValue())+1e-10);
