**The quest for small benchmarks for the chromatic sum problem**

W. Głazek, M. Kubale, K. Manuszewski(Technical University of Gdańsk, Poland ) |

*HCT*(resp.

*HCT*) if some (resp. every) implementation of the algorithm gives a bigger total than the chromatic sum. In this paper we give the smallest

*HCT*and slightly

*HCT*graphs for the most popular vertex coloring algorithms when adapted to the chromatic sum problem. Some of them have been obtained by exhaustive computational search. Our results confirm that algorithms based on the independent sets principle are much better than those realizing a sequential coloring approach.
