Integer Programming Formulations for the k-Cardinality Tree Problem

چکیده
In this paper, we present two Integer Programming formulations for the k-Cardinality Tree Problem. The first is a multiflow formulation while the second uses a lifting of the Miller-Tucker-Zemlin constraints. Based on our computational experience, we suggest a two-phase exact solution approach that combines two different solution techniques, each one exploring one of the proposed formulations.

Algorithms for the Maximum Weight Connected k -Induced Subgraph Problem
Finding differentially regulated subgraphs in a biochemical network is an important problem in bioinformatics. We present a new model for finding such subgraphs which takes the polarity of the edges (activating or inhibiting) into account, leading to the problem of finding a connected subgraph induced by k vertices with maximum weight. We present several algorithms for this problem, including d...
متن کاملSolving Single Machine Sequencing to Minimize Maximum Lateness Problem Using Mixed Integer Programming
Despite existing various integer programming for sequencing problems, there is not enoughinformation about practical values of the models. This paper considers the problem of minimizing maximumlateness with release dates and presents four different mixed integer programming (MIP) models to solve thisproblem. These models have been formulated for the classical single machine problem, namely sequ...
متن کاملA Mixed Integer Programming Approach to Optimal Feeder Routing for Tree-Based Distribution System: A Case Study
A genetic algorithm is proposed to optimize a tree-structured power distribution network considering optimal cable sizing. For minimizing the total cost of the network, a mixed-integer programming model is presented determining the optimal sizes of cables with minimized location-allocation cost. For designing the distribution lines in a power network, the primary factors must be considered as m...
متن کاملHypervolume Subset Selection in Two Dimensions: Formulations and Algorithms
The hypervolume subset selection problem consists of finding a subset, with a given cardinality k, of a set of nondominated points that maximizes the hypervolume indicator. This problem arises in selection procedures of evolutionary algorithms for multiobjective optimization, for which practically efficient algorithms are required. In this article, two new formulations are provided for the two-...
متن کاملOn the minimum-cost λ-edge-connected k-subgraph problem
In this paper, we propose several integer programming (IP) formulations to exactly solve the minimum-cost λ -edge-connected k-subgraph problem, or the (k,λ )-subgraph problem, based on its graph properties. Special cases of this problem include the well-known k-minimum spanning tree problem (if λ = 1), λ -edgeconnected spanning subgraph problem (if k = |V |) and k-clique problem (if λ = k−1 and...
