We consider in this paper a duopoly competing in quantities and where firms can invest in R&D to control their emissions. We distinguish between effort carri...
BibTeX referenceOn a Conjecture About the Szeged Index
Khalifeh, Yousefi-Azari, Ashrafi and Wagner [European J. Combin. 30 (2009) 1149-1163] conjectured that for a connected graph <i>G</i> on <i>n</i> vertices...

We propose a deterministic, discrete-time, finite-horizon oligopoly model to investigate investment and production equilibrium strategies, in a setting where...

The <i>improved primal simplex</i> (IPS) method has been proposed by Elhallaoui et al. (2008). We rewrite the theory of IPS for a cold start with an initial ...

This paper focuses on the use of different memory strategies to improve multistart methods. A network design problem in which the costs are given by discrete...

This work studies multi-objective optimization <i>(MOP)</i> of nonsmooth functions subject to general constraints. We first present definitions and optimalit...
