You should be able to download a trace of your preliminary matches,
and then view them locally. These aren't available for the random
matches, but, if you challenge another player to a match, both you and
that player will be able to download the trace.
After you log in and choose "View Your Results ...", you should be
able to get to the trace files from the "Match Results" at the top of
the page. It looks like, right now, the text of the trace file is
showing up right in the results page. (Some people have pointed out
that this is going to be a problem as results accumulate) For now,
you may have to cut-and-paste your results into a local file and then
view them with the TracePlayer. I think we'll see if we can do
something different for serving the trace files.
If you download a trace, trace.txt, you should be able to watch it
with:
java icpc.challenge.view.TracePlayer -trace trace.txt
That's assuming you've put coercion.jar in your CLASSPATH.
