Adaptive Partitioning in Column Generation for Nested Paths
Bart van Rossum, Rolf van Lieshout, Alexandre Jacquillat
We study a class of nested path problems, in which every path-based variable can be decomposed into a sequence of subpaths. Subpaths must satisfy local resources, while paths must…

Efficient Branching Rules for Optimizing Range and Order-Based Objective Functions
Bart van Rossum, Rui Chen, Andrea Lodi
We consider range minimization problems featuring exponentially many variables, as frequently arising in fairness-oriented or bi-objective optimization. While branch and price is s…
