  • Semidefinite optimization in power flow problems

    We are pleased to announce a MOSEK workshop on Semidefinite optimization in power flow problems taking place on Tuesday, February 28th, 2017 at the Symbion research park.Optimal power flow is one of the major problems in optimization of electric power systems, asking for the minimization of operating costs in terms of a specified objective function in the presence of non-linear power flow equation...

  • Modeling non-convex absolute value constraints with MILP

    We are being asked if one can use MOSEK to express a constraint of the form $$\label{eq:sumabs}\sum_i|x_i|=c$$ for some $x\in\mathbb{R}^n$ and $c\in\mathbb{R}$. This condition is non-convex; for instance for $n=1$ it is equivalent to $x=\pm c$. Such constraints appear in long-short portfolio optimization problems (see stackoverflow, paper).The idea is to introduce a binary vector indicating the po...
