Finding a Minimum-Weight k-Link Path in Graphs with the Concave Monge Property and Applications.
Finding -partitions efficiently
We study the concept of an -partition of the vertex set of a graph , which includes all vertex partitioning problems into four parts which we require to be nonempty with only external constraints according to the structure of a model graph , with the exception of two cases, one that has already been classified as polynomial, and the other one remains unclassified. In the context of more general vertex-partition problems, the problems addressed in this paper have these properties: non-list, -part,...
Finding H-partitions efficiently
We study the concept of an H-partition of the vertex set of a graph G, which includes all vertex partitioning problems into four parts which we require to be nonempty with only external constraints according to the structure of a model graph H, with the exception of two cases, one that has already been classified as polynomial, and the other one remains unclassified. In the context of more general vertex-partition problems, the problems addressed in this paper have these properties: non-list, 4-part, external...
Finding Minimum Area k-gons.
Full approximability of a class of problems over power sets.
In this paper results concerning structural and approximability properties of the subclass of NP-Complete Optimization Problems, defined over a lattice are considered. First, various approaches to the concept of Fully Polynomial Approximation Scheme are presented with application to several known problems in the class of NP-Complete Optimization Problems.Secondly, a characterization of full Approximability for the class of Max Subset Problems is introduced.
