A disproof of Henning's conjecture on irredundance perfect graphs
Let ir(G) and (G) be the irredundance number and the domination number of a graph G, respectively. A graph G is called irredundance perfect if ir(H) = (H), for every induced subgr...

Hamiltonian powers in threshold and arborescent comparability graphs
We examine powers of Hamiltonian paths and cycles as well as Hamiltonian (power) completion problems in several highly structured graph classes. For threshold graphs we give effic...

An Optimal Algorithm for the k-Fixed-Endpoint Path Cover on Proper Interval Graphs
In this paper we consider the k-fixed-endpoint path cover problem on proper interval graphs, which is a generalization of the path cover problem. Given a graph G and a set T of k v...

I/O Clustering in Design Cost and Performance Optimization for Flip-Chip Design
I/O placement has always been a concern in modern IC design. Due to flip-chip technology, I/O can be placed throughout the whole chip without long wires from the periphery of the...
