Two-Dimensional Phase Unwrapping via Balanced Spanning Forests
Ian Herszterg, Marcus Poggi, Thibaut Vidal
Phase unwrapping is the process of recovering a continuous phase signal from an original signal wrapped in the (,] interval. It is a critical step of coherent signal process…
Industrial and Tramp Ship Routing Problems: Closing the Gap for Real-Scale Instances
Gabriel Homsi, Rafael Martinelli, Thibaut Vidal +1
Recent studies in maritime logistics have introduced a general ship routing problem and a benchmark suite based on real shipping segments, considering pickups and deliveries, cargo…
An Efficient Matheuristic for the Minimum-Weight Dominating Set Problem
Mayra Albuquerque, Thibaut Vidal
A minimum dominating set in a graph is a minimum set of vertices such that every vertex of the graph either belongs to it, or is adjacent to one vertex of this set. This mathematic…
On three soft rectangle packing problems with guillotine constraints
Quoc Trung Bui, Thibaut Vidal, Minh Hoàng Hà
We investigate how to partition a rectangular region of length and height into rectangles of given areas using two-stage guillotine cuts, so as…
HG-means: A scalable hybrid genetic algorithm for minimum sum-of-squares clustering
Daniel Gribel, Thibaut Vidal
Minimum sum-of-squares clustering (MSSC) is a widely used clustering model, of which the popular K-means algorithm constitutes a local minimizer. It is well known that the solution…
Heuristics for vehicle routing problems: Sequence or set optimization?
Túlio A. M. Toffolo, Thibaut Vidal, Tony Wauters
We investigate a structural decomposition for the capacitated vehicle routing problem (CVRP) based on vehicle-to-customer "assignment" and visits "sequencing" decision variables. W…
