Both variants of the BACAP are modeled in this paper using a Generalized Set Partitioning (GSPP) formulation. Furthermore, a set of column reduction techniques are presented which help to limit the number of feasible columns generated and to provide better bounds. The literature on the BAP ...

This paper proposes a robust heuristic approach for the VRPTW using travel distance as the main objective through an efficient genetic algorithm and a set partitioning formulation. The tests were produced using real numbers and truncated data type, allowing a direct comparison of its results against ...
Based on this set partitioning formulation, branch-and-bound exact solution algorithms can be designed for these problems. In such a branch-and-bound tree... ZL Chen,WB Powell - 《Informs Journal on Computing》 被引量: 282发表: 1999年 Solving Parallel Machine Scheduling Problems by Column Gene...
In this paper, we propose an approach for multi-region segmentation based on a topological graph prior within a multi-level set (MLS) formulation. We consider topological graph prior information to evolve the contour based on a topological relationship presented via a graph relation. This novel me...

Our experiments on well-known classification and regression datasets show that the original set partitioning model formulation significantly reduces the number of rules while keeping the accuracy at acceptable levels. We also propose a modification to the problem's objective function, ...
In "The Complexity of the Pricing Problem of the Set Partitioning Formulation of Vehicle Routing Problems," it is proven by Remy Spliet that the pricing problem is strongly NP hard for many different vehicle routing problems. This means that, unless P = NP, no pseudopolynomial...
