A Lagrange decomposition based Branch and Bound algorithm for the Optimal Mapping of Cloud Virtual Machines
Guanglei Wang, Walid Ben-Ameur, Adam Ouorou
One of the challenges of cloud computing is to optimally and efficiently assign virtual ma- chines to physical machines. The aim of telecommunication operators is to minimize the m…
Exploiting sparsity for the min k-partition problem
Guanglei Wang, Hassan Hijazi
The minimum k-partition problem is a challenging combinatorial problem with a diverse set of applications ranging from telecommunications to sports scheduling. It generalizes the m…
Multipolar robust optimization
Walid Ben-Ameur, Adam Ouorou, Guanglei Wang +1
We consider linear programs involving uncertain parameters and propose a new tractable robust counterpart which contains and generalizes several other models including the existing…
Adjustably Robust Optimal Power Flows with Demand Uncertainty via Path-based Flows
Jakub Marecek, Adam Ouorou, Guanglei Wang
We study the optimal power flow problem with switching (or, equivalently, the line expansion problem) under demand uncertainty. Specifically, we consider the line-use variables at…
