An Efficient Merge Search Matheuristic for Maximising the Net Present Value of Project Schedules

no code implementations20 Oct 2022 Dhananjay R. Thiruvady, Su Nguyen, Christian Blum, Andreas T. Ernst

This paper presents a novel matheuristic framework designed for resource constrained project scheduling, Merge search, which is a variable partitioning and merging mechanism to formulate restricted mixed integer programs with the aim of improving an existing pool of solutions.

Synergistic Team Composition: A Computational Approach to Foster Diversity in Teams

no code implementations26 Sep 2019 Ewa Andrejczuk, Filippo Bistaffa, Christian Blum, Juan A. Rodríguez-Aguilar, Carles Sierra

Thus, the goal of the STCP is to partition a set of individuals into a set of synergistic teams: teams that are diverse in personality and gender and whose members cover all required competencies to complete a task.

Generic CP-Supported CMSA for Binary Integer Linear Programs

no code implementations30 May 2018 Christian Blum, Haroldo Gambini Santos

Moreover, the results indicate that the support of the constraint propagation engine is useful in the context of problems for which finding feasible solutions is rather difficult.
