Estimating causal effects with optimization-based methods: A review and empirical comparison

In the absence of randomized controlled and natural experiments, it is necessary to balance the treated and control groups in order to estimate an unbiased causal effect of interest; otherwise, an opposite effect may be estimated, and incorrect …

RWA problem with geodesics in realistic OTN topologies

This paper presents a decomposition approach for solving a variant of the routing and wavelength assignment (RWA) problem, in which all connection requests are covered by geodesics, i.e., shortest paths with respect to the number of hops. Our …

Optimisation du routage et de l'affectation de longueurs d'onde sur un réseau de télécommunication par programmation mathématique

This work presents a decomposition approach for solving a variant of the routing and wavelength assignment problem, in which all connection requests are covered by shortest paths with respect to the number of hops. Our variant consists in minimizing …
