| abstract: |
A strong stable set in a graph
G
is a stable set that contains a vertex of every
maximal clique of
G
. A Meyniel obstruction is an odd circuit with at
least five vertices and at most one chord. Given a graph
G
and a vertex
v
of
G
, we give a polytime algorithm to find either a
strong stable set containing
v
or a Meyniel obstruction in
G
. This can then be used to find in any graph, a
clique and colouring of the same size or a Meyniel
obstruction.

The first source gives you the `gzipped' PostScript, the second the plain PostScript and the third the format for the Adobe accrobat reader. Depending on the installation of your web browser, at least one of these should (after some amount of time) pop up a window for you that shows the full article. If this is not the case, you should contact your system administrator to install your browser correctly.
Due to limitations of your local software, the two formats may show up differently on your screen. If eg you use xpdf to visualize pdf, some of the graphics in the file may not come across. On the other hand, pdf has a capacity of giving links to sections, bibliography and external references that will not appear with PostScript.
