Enhanced Methods for the Weight Constrained Shortest Path Problem

1 code implementation29 Jul 2022 Saman Ahmadi, Guido Tack, Daniel Harabor, Philip Kilby, Mahdi Jalili

This paper leverages the recent state-of-the-art techniques in both constrained pathfinding and bi-objective search and presents two new solution approaches to the WCSPP on the basis of A* search, both capable of solving hard WCSPP instances on very large graphs.

Bi-objective Search with Bi-directional A*

no code implementations25 May 2021 Saman Ahmadi, Guido Tack, Daniel Harabor, Philip Kilby

Bi-objective search is a well-known algorithmic problem, concerned with finding a set of optimal solutions in a two-dimensional domain.

Versatile and Robust Transient Stability Assessment via Instance Transfer Learning

no code implementations20 Feb 2021 Seyedali Meghdadi, Guido Tack, Ariel Liebman, Nicolas Langrené, Christoph Bergmeir

To support N-1 pre-fault transient stability assessment, this paper introduces a new data collection method in a data-driven algorithm incorporating the knowledge of power system dynamics.

Solution Dominance over Constraint Satisfaction Problems

no code implementations21 Dec 2018 Tias Guns, Peter J. Stuckey, Guido Tack

We define Constraint Dominance Problems (CDPs) as CSPs with a dominance relation, that is, a preorder over the solutions of the CSP.
