Integral solutions during root node solving with primal simplex?

  • 1.  Integral solutions during root node solving with primal simplex?

    Hello everybody,

    I just asked myself whether (perhaps non-optimal) integral solutions could appear during the simplex iterations in the root node when I use the primal simplex algorithm as root node algorithm.

    I wanted to check this using an LP-callback but then I saw that I was not able to obtain the values of the variables during the root node LP solution process. So my questions are:

    1. Does it make sense to check this?
    2. Does CPLEX check this?
    3. Is there a way to obtain the values of the variables between the primal simplex iterations?

    Best regards,
    Thomas
