Avoiding unsafe states in manufacturing systems based on polynomial digraph algorithms
Abstract − A deadlock-free unsafe (DFU) state of Resource Allocation System (RAS) is deadlock-free but inevitable to enter a deadlock state. Previous research revealed that in ma...

Note on alternating directed cycles
The problem of the existence of an alternating simple dicycle in a 2-arc-coloured digraph is considered. This is a generalization of the alternating cycle problem in 2-edgecoloure...

The Diameter of Randomly Perturbed Digraphs and Some Applications.
The central observation of this paper is that if ǫn random arcs are added to any n-node strongly connected digraph with bounded degree then the resulting graph has diameter O(ln ...

Generating Paths and Cuts in Multi-pole (Di)graphs
Let G = (V, E) be a (directed) graph with vertex set V and edge (arc) set E. Given a set P of (source-sink) pairs of vertices of G, an important problem that arises in the computat...

On Theorems Equivalent with Kotzig's Result on Graphs with Unique 1-Factors
We show that several known theorems on graphs and digraphs are equivalent. The list of equivalent theorems include Kotzig's result on graphs with unique 1-factors, a lemma by...
