    dear mr.

    I want to get integer solution

    I heard ,
    first, make a problem with int variable
    and then make it relax can help like this problem..

    CPLEX's MIP algorithm will relax your integer program as it tries to solve it, so you don't
    need to do that yourself.  If CPLEX's default parameter settings don't find an integer
    solution to your problem, try setting the MIP emphasis parameter to 1, which instructs
    CPLEX to use strategies that focus on finding integer solutions.  Also, try the 'feasopt'
    feature, which solves an auxiliary model related to your problem that can find a feasible solution to your actual model.
