多目标整数线性最优化的部分Gröbner基

Partial Gröbner bases for multiobjective integer linear optimization

Victor Blanco, Justo Puerto

摘要:

在本文中,我们提出了一个新的方法来解决多目标整数线性规划的工具,代数几何。我们引入了部分Gröbner基的概念,为一个家庭的多目标规划的右手边变化。这种新结构将单目标情形的Gröbner基概念扩展到多目标情形,即,一个偏序而不是可行向量的全序。这些基的主要性质是约束矩阵的核中的整数元素通过基的不同块的部分减少为零。它使我们能够证明,这个新的建设是一个家庭的多目标程序的测试家庭。一个算法'à la Buchberger'的开发来计算部分Gröbner基地和两种不同的方法,使用这种方法,计算任何多目标整数线性问题(MOILP)的整个有效解集。一些例子说明了应用的算法和计算实验报告的几个家庭的问题。

英文摘要:

In this paper we present a new methodology for solving multiobjective integer linear programs using tools from algebraic geometry. We introduce the concept of partial Gröbner basis for a family of multiobjective programs where the right-hand side varies. This new structure extends the notion of Gröbner basis for the single objective case, to the case of multiple objectives, i.e., a partial ordering instead of a total ordering over the feasible vectors. The main property of these bases is that the partial reduction of the integer elements in the kernel of the constraint matrix by the different blocks of the basis is zero. It allows us to prove that this new construction is a test family for a family of multiobjective programs. An algorithm 'à la Buchberger' is developed to compute partial Gröbner bases and two different approaches are derived, using this methodology, for computing the entire set of efficient solutions of any multiobjective integer linear problem (MOILP). Some examples illustrate the application of the algorithms and computational experiments are reported on several families of problems.
