Adaptive large neighborhood search for mixed integer programming
Large Neighborhood Search (LNS) heuristics are among the most powerful but also most expensive heuristics for mixed integer programs (MIP). Ideally, a solver adaptively concentrates its limited computational budget by learning which LNS heuristics work ...

Optimization as an analysis tool for human complex decision making [PDF]
We present a problem class of mixed-integer nonlinear programs (MINLPs) with nonconvex continuous relaxations which stem from economic test scenarios that are used in the analysis of human complex problem solving.

Optimizing electricity distribution using two-stage integer recourse models [PDF]
We consider two planning problems faced by an electricity distributor. Electricity can be ob-tained both from power plants and small generators such as hospitals and greenhouses, whereas the future demand for electricity is uncertain.

Branch-and-price and heuristic column generation for the generalized truck-and-trailer routing problem [PDF]
The generalized truck-and-trailer routing problem (GTTRP) constitutes a uni¯ed model for vehicle routing problems with trailers and a fixed lorry-trailer assignment.

On multiple simple recourse models [PDF]
We consider multiple simple recourse (MSR) models, both continuous and integer versions, which generalize the corresponding simple recourse (SR) models by allowing for a refined penalty cost structure for individual shortages and surpluses.

Undecidability and hardness in mixed-integer nonlinear programming
We survey two aspects of mixed-integer nonlinear programming which have attracted less attention (so far) than solution methods, solvers and applications: namely, whether the class of these problems can be solved algorithmically, and, for the subclasses ...

Integrated chance constraints in an ALM model for pension funds [PDF]
We discuss integrated chance constraints in their role of short-term risk constraints in a strategic ALM model for Dutch pension funds. The problem is set up as a multistage recourse model, with special attention for modeling the guidelines proposed by ...

Relaxations of mixed integer sets from lattice-free polyhedra [PDF]
This paper gives an introduction to a recently established link between the geometry of numbers and mixed integer optimization. The main focus is to provide a review of families of lattice-free polyhedra and their use in a disjunctive programming ...
