New benchmark instances for the Capacitated Vehicle Routing Problem

The recent research on the CVRP is being slowed down by the lack of a good set of benchmark instances. The existing sets suffer from at least one of the following drawbacks: (i) became too easy for current algorithms; (ii) are too artificial; (iii) are too homogeneous, not covering the wide range of characteristics found in real applications. We propose a new set of instances ranging from 100 t...

Clustering Aggregation as Maximum-Weight Independent Set

We formulate clustering aggregation as a special instance of Maximum-Weight Independent Set (MWIS) problem. For a given dataset, an attributed graph is constructed from the union of the input clusterings generated by different underlying clustering algorithms with different parameters. The vertices, which represent the distinct clusters, are weighted by an internal index measuring both cohesion...

Segmentation as Maximum-Weight Independent Set

Given an ensemble of distinct, low-level segmentations of an image, our goal is to identify visually “meaningful” segments in the ensemble. Knowledge about any specific objects and surfaces present in the image is not available. The selection of image regions occupied by objects is formalized as the maximum-weight independent set (MWIS) problem. MWIS is the heaviest subset of mutually non-adjac...

Hybrid Heuristic for the Maximum-Weight Independent Set Problem

We propose an approximate algorithm for finding the maximum-weight independent set of a given graph of n nodes with associated weights. It combines three different heuristics, and its running time is O(n2) in the practice. We also propose a set of random graphs for testing and comparing the maximumweight independent set algorithms. This graphs are easy to identically generate on any computer ca...

A Variant of the Maximum Weight Independent Set Problem

We study a natural extension of the Maximum Weight Independent Set Problem (MWIS), one of the most studied optimization problems in Graph algorithms. We are given a graph G = (V,E), a weight function w : V → R, a budget function b : V → Z, and a positive integer B. The weight (resp. budget) of a subset of vertices is the sum of weights (resp. budgets) of the vertices in the subset. A k-budgeted...
