A Note on Circular Arc Online Coloring using First Fit
نویسنده
چکیده
In [1] using a column construction technique it is proved that every interval graph can be colored online with First Fit with at most 8w(G) colors, where w(G) is the size of the maximum clique of G. Since the column construction can not be adapted to circular arc graphs we give a different proof to establish an upper bound of 9w(G) for online coloring a circular arc graph G with the First Fit algorithm.

Efficient Approximation Algorithms for Domatic Partition and On-Line Coloring of Circular Arc Graphs
We exploit the close relationship between circular arc graphs and interval graphs to design efficient approximation algorithms for NP-hard Optimization problems on circular arc graphs. The problems considered here are maximum domatic partition and on-line minimum vertex coloring. We present a heuristic for the domatic partition problem with a performance ratio of 4. For on-line coloring, we con...
متن کاملComparing First-Fit and Next-Fit for Online Edge Coloring
We study the performance of the algorithms First-Fit and Next-Fit for two online edge coloring problems. In the min-coloring problem, all edges must be colored using as few colors as possible. In the max-coloring problem, a fixed number of colors is given, and as many edges as possible should be colored. Previous analysis using the competitive ratio has not separated the performance of First-Fi...
متن کاملOn k-Coloring of Weighted Circular-Arc Graphs
The problem of coloring a subgraph of any weighted circular-arc graph with a set of k colors is studied in this paper. In such a coloring, two overlapping arcs must receive different colors. Our main result is to derive a 2-approximation algorithm for the NP-hard problem of finding a maximum total weight k-colorable subgraph of any weighted circular-arc graph, and this algorithm runs in O(mloge...
متن کاملPerfect Circular Arc Coloring
The circular arc coloring problem is to find a minimum coloring of a set of arcs of a circle so that no two overlapping arcs share a color. This N P-hard problem arises in a rich variety of applications and has been studied extensively. In this paper we present an O(n2m) combinatorial algorithm for optimally coloring any set of arcs that corresponds to a perfect graph, and propose a new approac...
متن کاملA note on the Hadwiger number of circular arc graphs
The intention of this note is to motivate the researchers to study Hadwiger’s conjecture for circular arc graphs. Let η(G) denote the largest clique minor of a graph G, and let χ(G) denote its chromatic number. Hadwiger’s conjecture states that η(G) ≥ χ(G) and is one of the most important and difficult open problems in graph theory. From the point of view of researchers who are sceptical of the...
