    Hi,

     

    I create an LP file to see if the model is created in a correct way in Java API. However, the objective function contains the variables which are associated with zero-coefficients and that makes it hard for me to analyze the model. I was wondering if there is any way that I can only see the variables with non-zero coefficients.

    Within your Java program, if "cplex" is the name of your IloCplex instance, you could just print cplex.getObjective(). That would print a human-readable version without any terms having zero coefficients.
