Using a fixed set of colors
C
, Ann and Ben color the edges of a graph
G
so that no monochromatic cycle may appear. Ann wins
if all edges of
G
have been colored, while Ben wins if completing a
coloring is not possible. The minimum size of
C
for which Ann has a winning strategy is called the
game arboricity of
G
, denoted by
A
. We prove that
g
(G)
A
for any graph
g
(G) ≤3k
G
of arboricity
k
, and that there are graphs such that
A
. The upper bound is achieved by a suitable version
of the activation strategy, used earlier for the vertex
coloring game. We also provide other strategie based on
induction.

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.
