PrecPack: An Efficient Open-Source Exact Solver for Bin Packing with Generalized Precedence Constraints
Sunkanghong Wang, Zhengzhong Ricky You, Roberto Baldacci +4
Efficient resource use in packing and assembly-line applications requires decisions that jointly account for capacity and precedence constraints. The strongly NP-hard bin packing p…
Advancing Branch-and-Price for Graph Coloring: New Pricing Strategies and Benchmark Results
Mingming Zheng, Roberto Baldacci, Fabio Furini +1
This paper proposes BPCOL+, an exact branch-and-price algorithm for the Graph Coloring Problem. The algorithm integrates enhanced pricing strategies based on Zero-Suppressed Binary…
A Tight 2-Approximation Algorithm for the Bin Packing Problem with Setups
Roberto Baldacci, Fabio Ciccarelli, Stefano Coniglio +2
We study approximation algorithms for the Bin Packing Problem with Setups (BPPS), a generalization of the classical Bin Packing Problem (BPP) in which items are partitioned into cl…
The Bin Packing Problem with Setups: Formulations, Structural Properties and Computational Insights
Roberto Baldacci, Fabio Ciccarelli, Stefano Coniglio +2
We introduce the Bin Packing Problem with Setups (BPPS), a generalization of the classical Bin Packing Problem with applications in production planning and logistics. In this probl…
