Some new results on minimum cycle covers are proved. As a consequence, it is obtained that the edges of a bridgeless graph G can be covered by cycles of total length at most |E(G)| + 25 24 (|V (G)| -1), and at most |E(G)| + |V (G)| -1 if G contains no circuit of length 8 or 12.

## Abstract Halin graphs are planar 3βconnected graphs that consist of a tree and a cycle connecting the end vertices of the tree. It is shown that all Halin graphs that are not βnecklacesβ have a unique minimum cycle basis. Β© 2003 Wiley Periodicals, Inc. J Graph Theory 43: 150β155, 2003
The problem of minimum color sum of a graph is to color the vertices of the Ε½ . graph such that the sum average of all assigned colors is minimum. Recently it was shown that in general graphs this problem cannot be approximated within 1y β Ε½ n , for any β ) 0, unless NP s ZPP Bar-Noy et al., Informa
## Abstract We write __H__βββ__G__ if every 2βcoloring of the edges of graph __H__ contains a monochromatic copy of graph __G__. A graph __H__ is __G__β__minimal__ if __H__βββ__G__, but for every proper subgraph __H__β² of __H__, __H__β²βββ__G__. We define __s__(__G__) to be the minimum __s__ such th
Pullman [3] conjectured that if k is an odd positive integer, then every orientation of a regular graph of degree k has a minimum decomposition which contains no vertex which is both the initial vertex of some path in the decomposition and the terminal vertex of some other path in the decomposition
