Callback codes in continuous nonconvex QCQPs

    Hi Gonzalo,

    Yes, your interpretation is correct - the MIPNODE callback indicates the exploration of a spatial branch-and-bound node, and the MIPSOL callback indicates that a new QCQP-feasible solution was found. You can think of the continuous variables in the product terms of non-convex quadratic constraints or in a non-convex quadratic objective as "integer" variables, since Gurobi branches on these variables, effectively solving the problem like a MIP.

    Thanks,

    Eli
