In this paper, we consider size-constrained minimum s–t cut problems and size-constrained dense subgraph problems. We introduce the minimum s–t cut with at-least-k vertices problem, the minimum s–t cut with at-most-k vertices problem, and the minimum s–t cut with exactly k vertices problem. We prove that they are NP-complete. Thus, they are not polynomially solvable unless P=NP. On the other hand, we also study the densest at-least-k-subgraph problem (DalkS) and the densest at-most-k-subgraph problem (DamkS) introduced by Andersen and Chellapilla [1]. We present a polynomial time algorithm for DalkS when k is bounded by some constant c. We also present two approximation algorithms for DamkS. The first approximation algorithm for DamkS has an approximation ratio of n−1k−1, where n is the number of vertices in the input graph. The second approximation algorithm for DamkS has an approximation ratio of O(nδ), for some δ<1/3.}, journal={THEORETICAL COMPUTER SCIENCE}, author={Chen, Wenbin and Samatova, Nagiza F. and Stallmann, Matthias F. and Hendrix, William and Ying, Weiqin}, year={2016}, month={Jan}, pages={434–442} }

The objective is to locate p supply points in order to minimize the total distance of the demand points to their nearest supply point. p-Median is polynomially solvable in one dimension but NP-hard in two or more dimensions, when either the Euclidean or the rectilinear distance measure is used. In this paper, we treat the p-median problem under a new distance measure, the directional rectilinear distance, which requires the assigned supply point for a given demand point to lie above and to the right of it. In a previous work, we showed that the directional p-median problem is polynomially solvable in one dimension; we give here an improved solution through reformulating the problem as a special case of the constrained shortest path problem. We have previously proven that the problem is NP-complete in two or more dimensions; we present here an efficient heuristic to solve it. Compared to the robust Teitz and Bart heuristic, our heuristic enjoys substantial speedup while sacrificing little in terms of solution quality, making it an ideal choice for real-world applications with thousands of demand points.}, number={3}, journal={EUROPEAN JOURNAL OF OPERATIONAL RESEARCH}, author={Jackson, Laura E. and Rouskas, George N. and Stallmann, Matthias F.

The most recent and rather comprehensive comparisons between UnitWalk and several versions of WalkSAT demonstrate that neither solver dominates on all benchmarks. QingTing2 (a ‘dragonfly’ in Mandarin) is a SAT solver script that relies on a novel switching strategy to invoke one of the two local search solvers: WalkSAT or QingTing1. The local search solver QingTing1 implements the UnitWalk algorithm with a new unit-propagation technique. The experimental methodology we use not only demonstrates the effectiveness of the switching strategy and the efficiency of the new unit-propagation implementation – it also supports, on the very same instances, statistically significant performance evaluation between local search and other state-of-the-art DPLL-based SAT solvers. The resulting comparisons show a surprising pattern of solver dominance, completely unanticipated when we began this work.}, booktitle={Theory and Applications of Satisfiability Testing}, publisher={Springer Berlin Heidelberg}, author={Li, Xiao Yu and Stallmann, Matthias F. and Brglez, Franc}, year={2004}, pages={53–68} }

We show that the performance ratio for the barycenter heuristic is still Ω(n) even for connected bipartite graphs.

Recent investigations have shown, however, that the computational effort of many network-oriented project management techniques depends strongly on the so-called complexity index (CI) of a network. We show other justifications for minimizing the CI rather than the number of dummy arcs. We also present a polynomial time algorithm for constructing an AoA network with the minimum CI in the class of all AoA networks having the minimum number of nodes. © 2000 John Wiley & Sons, Inc.

We consider the case where both V 0 and V 1 can be permuted arbitrarily — both this and the case where the order of one vertex set is fixed are NP-hard. Two new heuristics that perform well on sparse graphs such as occur in circuit layout problems are presented. The new heuristics outperform existing heuristics on graph classes that range from application-specific to random. Our experimental design methodology ensures that differences in performance are statistically significant and not the result of minor variations in graph structure or input order.}, booktitle={Algorithm Engineering and Experimentation: International workshop ALENEX '99, Baltimore, MD, USA, Jan. 15-16, 1999.}, publisher={Berlin; New York: Springer}, author={Stallmann, Matthias and Brglez, F. and Ghosh, D.}, year={1999}, pages={74–93} }
