Greetings...
Since last issue, Pihlaja has extended his self-organising maps to cover all
of the Koenigstuhl hills. Analysis would be welcome in either the newsgroup
or in a future CW issue. They are available from:
http://www.cs.helsinki.fi/u/jpihlaja/cw/maps/
This issue we have the results from the third round of the tournament and
also, the code for Reepicheep...

145 challenges have passed since last issue causing the retirement of our
three most elderly warriors, all of which have been King of the Hill.
nPaper is the oldest warrior ever to sit in the top rank, while at an impressive
age of 925! (2nd comes Son of Vain which was age 830, 3rd Quicksilver at 759.)
Most seen as KotH since last issue have been Reepicheep (37 times), closely
followed by pTest4 (36 times), Vanquisher (20), oneshot test (19) and
Hazy Lazy ... again (16).
Finally then, the complete list of aged warriors to perish: nPaper II (age
1270), Behemot (1078), Olivia (886), Inky (736), G3-b (503), Purifier (277),
QSOS (126), pre75-z47a (120) and Terra (104).

Spring / Summer 2002 Corewar Tournament - Round 3 Results:
Once again there are 17 entries from 9 authors, this time competing using
'88 standard redcode, coresize 8000. To reduce the advantage imp warriors
seem to enjoy in the '88 environment, the rules for round 3 differ in two
ways from the settings of the '88 standard hill at KotH.
In round 3 a tie is not declared until 800000 cycles have passed. Also, a
win is worth 6 points instead of the more usual 3. But will this be enough
to discorage tie-prone warriors? Each pair of warriors battled for 4000
rounds. 14 hours, 51 minutes and 03 seconds later we have our answer...
Janeczek takes first place with Quicksilver '88 (qscan -> stone/imp) while
Wainwright's Return to the Citadel (qscan -> paper/imp) takes second place.
Once again Hillis evolves a formidable opponent to claim third. Stone/imps
feature again in ranks 4 (Espiritu's) and 6 (Gunnell's). Ford, Thorne and
Grabun are next, each with a dat bomber. Finally, we have a .4c vampire
with airbag from Moore.

Extra Extra - Reepicheep by Lukasz Grabun / John Metcalf
It has been becoming increasingly rewarding of late to team up with fellow
redcoders and cooperate on a warrior project. Reepicheep (named in honour
of the famed Narnia mouse) is the successful result of one such project,
being an aggressive stone/paper warrior. One aim is to ensure each part
is only as large/complex as neccessary.
The stone is similar to the one used by Candy, <.5c and self-bombing to
become a clear. A variety of other stone types were tested, including a
faster <.6c stone. However, the Candylike stone performs similarly, so
better meets our criteria.
The paper is similar to Unrequited Love. The attack comprises a single
bombing instruction which covers a strip of core with anti-3-point-imp dat
bombs. Variants with additional bombing instructions (similar to Pulp)
also prove equally effective, though not meeting our requirements. Note
the behaviour of the instruction marked pSilk2.
We hope to see a few more competitors scoring well on the hills with joint
creations. Finally then, the code:
