Is there any parameter that could be set in CPLEX to solve the linear relaxation of a MILP Problem? I have Cplex 9.0, and i can´t fin it in the documentation.

Thanks for your help

One simple idea would be to limit the number of nodes explored to 0 so that cplex would solve only the root relaxation.

The parameter for to set that is "CPX_PARAM_NODELIM" or "NodeLim".

You can then get the values of the model variables using IloCplex::getValue(...).
