Different Optimal Solutions from Equivalent Quadratic and Direct Formulations
AnsweredHi all, First of all, I hope I create this post in the correct community section. I’m working on a mixed-integer quadratic program (MIQP) to minimize an objective function representing the squared ...

Fractional Solution in Continuous Relaxation of Convex Quadratic Programming
AnsweredHi, I applied a convex quadratic function with linear constraints. The decision variable is set to continuous. In Gurobi method, I choose set model.Params.Method = 0 which I believe is primal simpl...
