A New Branch-and-Price-and-Cut Algorithm for One-Dimensional Bin-Packing Problems

open access: yesINFORMS Journal on Computing, 2020
In this paper, a new branch-and-price-and-cut algorithm is proposed to solve the one-dimensional bin-packing problem (1D-BPP). The 1D-BPP is one of the most fundamental problems in combinatorial optimization and has been extensively studied for decades ...

Solving Linear Integer Models with Variable Bounding

open access: yesForecasting, 2023
We present a technique to solve the linear integer model with variable bounding. By using the continuous optimal solution of the linear integer model, the variable bounds for the basic variables are approximated and then used to calculate the optimal ...
