Efficient neighborhood evaluation for the maximally diverse grouping problem

Schulz, Arne - In: Annals of Operations Research 341 (2024) 2, pp. 1247-1265

The Maximally Diverse Grouping Problem is one of the well-known combinatorial optimization problems with applications in the assignment of students to groups or courses. Due to its NP-hardness several (meta)heuristic solution approaches have been presented in the literature. Most of them include...

Original optimal method to solve the all-pairs shortest path problem: Dhouib-matrix-ALL-SPP

Dhouib, Souhail - In: Data science and management : DSM 7 (2024) 3, pp. 206-217

The All-pairs shortest path problem (ALL-SPP) aims to find the shortest path joining all the vertices in a given graph. This study proposed a new optimal method, Dhouib-matrix-ALL-SPP (DM-ALL-SPP) to solve the ALL-SPP based on column-row navigation through the adjacency matrix. DM-ALL-SPP is...
