Exploiting Packing Components in General-Purpose Integer Programming Solvers
Jakub Marecek
The problem of packing boxes into a large box is often a part of a larger problem. For example in furniture supply chain applications, one needs to decide what trucks to use to tra…
Matrix Completion under Interval Uncertainty
Jakub Marecek, Peter Richtarik, Martin Takac
Matrix completion under interval uncertainty can be cast as matrix completion with element-wise box constraints. We present an efficient alternating-direction parallel coordinate-d…
Signalling and obfuscation for congestion control
Jakub Marecek, Robert Shorten, Jia Yuan Yu
We aim to reduce the social cost of congestion in many smart city applications. In our model of congestion, agents interact over limited resources after receiving signals from a ce…
Distributed Block Coordinate Descent for Minimizing Partially Separable Functions
Jakub Marecek, Peter Richtarik, Martin Takac
In this work we propose a distributed randomized block coordinate descent method for minimizing a convex function with a huge number of variables/coordinates. We analyze its comple…
Optimal Power Flow as a Polynomial Optimization Problem
Bissan Ghaddar, Jakub Marecek, Martin Mevissen
Formulating the alternating current optimal power flow (ACOPF) as a polynomial optimization problem makes it possible to solve large instances in practice and to guarantee asymptot…
r-Extreme Signalling for Congestion Control
Jakub Marecek, Robert Shorten, Jia Yuan Yu
In many "smart city" applications, congestion arises in part due to the nature of signals received by individuals from a central authority. In the model of Marecek et al. [arXiv:14…
