Graph Subcolorings: Complexity and Algorithms
In a graph coloring, each color class induces a disjoint union of isolated vertices. A graph subcoloring generalizes this concept, since here each color class induces a disjoint un...

An adjustable linear time parallel algorithm for maximum weight bipartite matching
We present a parallel algorithm for finding a maximum weight matching in general bipartite graphs with an adjustable time complexity of O(n ) using O(nmax(2,4+)) processing

Characterizations and Linear Time Recognition of Helly Circular-Arc Graphs
Abstract. A circular-arc model (C, A) is a circle C together with a collection A of arcs of C. If A satisfies the Helly Property then (C, A) is a Helly circular-arc model. A (Helly...

On the computational complexity of partial covers of Theta graphs
By use of elementary geometric arguments we prove the existence of a special integral solution of a certain system of linear equations. The existence of such a solution yields the...

Reducing the Complexity of ILP Formulations for Synthesis
Integer Linear Programming ILP is commonly used in high level and system level synthesis. It is an NP-Complete problem in general cases. There exists some tools that give an o...
