New exact solution approaches for the split delivery vehicle routing problem
EURO Journal on Computational Optimization, 2018 In this study, we propose exact solution methods for the split delivery vehicle routing problem (SDVRP). We first give a new vehicle-indexed flow formulation for the problem and then a relaxation obtained by aggregating the vehicle-indexed variables over

Bilevel programming for price-based electricity auctions: a revenue-constrained case
EURO Journal on Computational Optimization, 2015 This paper describes the application of bilevel programming to a class of real-life problems in the field of electric power systems. Within the context of electricity markets, market-clearing procedures, i.e., auction models, are used by an independent ...

New Estimates On Various Critical/Universal Quantities of the 3D Ising Model [PDF]
, 1997 We present estimates for the 3D Ising model on the cubic lattice, both regarding interface and bulk properties. We have results for the interface tension, in particular the amplitude sigma0 in the critical law sigma = sigma0*t**mu, and for the universal ...

Complementarity-based nonlinear programming techniques for optimal mixing in gas networks
EURO Journal on Computational Optimization, 2019 We consider nonlinear and nonsmooth mixing aspects in gas transport optimization problems. As mixed-integer reformulations of pooling-type mixing models already render small-size instances computationally intractable, we investigate the applicability of ...
