Greetings...

There has been an abundance of interesting code published since last issue,
not least Sunset and Mantrap Arcade.  These two p-warriors are holding the
first two ranks on Koth's draft hill as well as the Koenigstuhl P-Space
and Open hills.  Three new warriors enter the top 10 on the infinite '94nop
hill, Numb, RotPendragon 2 and Candy II.

Chip Wendell has released a feature-packed new Mars for Windows, boasting
such facilities as read/write limits and random core size.  If you haven't
done so already, drop into the homepage and download a copy:

Rounds 9 and 10 of the ongoing tournament have taken place, with the
Limited Value round being won by Jakub Kozisek, and the Tri-Tiny round
by Dave Hillis.  German Labarga takes first place, climbing 4, followed
by Roy van Rijn who remains in second place.

Koen Struyve has organised the Corewars Beginner's League, a regular
tournament specifically for beginners.  For more info see:

Thanks this issue to Christian Schmidt, who discusses Quick-Scanners and
Paper in the hint, as well as sharing the code for unheard-of.

Since last issue, there have been 192 successful challenges and 10 warriors
have passed on, aged 100+.  Revenge of the Papers left the hill age 605.
Also leaving the hill this issue were Firestorm (age 589), Claw (525),
Dawn (350), Pixie (282), Driftwood (250), RotPendragon 2 (183), My First
Paper (168), Back To PolyLand (165) and Harmony Snoot (131).

Koth report:  Most often seen at the top of the hill has been Recon 2,
king after 162 successful challenges.  Reepicheep took first place after
12 challenges, and Thunderstrike after 10.  Son of Vain briefly took the
number one spot to once again break it's own record for the oldest KotH!
The oldest warriors ever to be seen in first place have been:

61 successful challenges have passed since last issue.  Mantrap Arcade held
the top of the hill for 7 challenges, before Sunset appeared.  David Moore's
p-switcher claimed first place on arrival, and hasn't once dropped below,
being at the top for all 50 challenges.  CrazyShot 2 perished (age 249), as
did Blowrag (192), Incredible! (180) and Microvenator (122).

Sunset has an impressive average score of 154.02, with individual scores
ranging from 147 to 165.  It has held, at the very least, a 3 point lead
over second place and switches between a scanner with anti-imp scan-step
and a paper/stone.  With the code published however, how long will Sunset
remain King?

Every Sunday at 7:00pm (GMT) Corewar folk from here, there and everywhere
gather in #COREWARS on IRC.KOTH.ORG to chat about all things Corewar.  With
so many Redcoders together at once, it was only a matter of time before
they wished to compare their Redcoding skills - the 30 minute tournament
was born.

Typically participants have to create a competitive warrior for an unusual
environment, or using a tricky subset of Redcode, with less time available
than most players take to select a name or tweak the boot distance!  An
average of 7 Redcoders play each week with the record to date being 12.

The Hint - Paper and Quick-Scanner by Christian Schmidt

If you're working on a successful paper, usually you will test/benchmark
your idea against scanners and oneshots to be sure the constants are well
chosen.  If you have finalized your paper, don't sit back and relax,
because that's not all that can be done!!!

This article focuses on the use of an additional quick-scanner beside the
paper.  "Well, I know" one could say, "nobody would write a paper without a
quick-scanner".  But nothing is published so far about the influence in
scoring if it is used.

Some of the advantages are evident.  The paper will gain some more wins
even if it battles against another paper (which usually ends close to 100%
ties).  Also, keep in mind modern quick-scanning warriors win about 10-15%
of the battle (if fighting against another quick-scanning warrior) only
with their quick-scanning part.

But how is the situation against a scanner?  Usually they don't use a
quick-scanner.  One effect should be that the quickscanner part acts
additionally as a decoy which should be good against scanner.  But how
strong is the influence in reality?  To answer this question, I decided to
have a closer look, focusing on a variety of different papers and scanners.

The aspect we want to figure out first is:  How much influence a decoy has
on the scoring of a paper against scanner.  Usually they should score
slightly better, because the scanner will be entraped to wipe the "useless"
decoy and give the paper a bit more time for a lucky hit or to gain enough
processes to survive.

The test warriors looks like:


;code of the paper is here (copy'n'pasted from the original source. Also
                            includes the original bootstrapping)


Decoy equ length

for (85-Decoy)
dat 0, 0
rof

i for Decoy
dat <i, >-i
rof

end


The following scanner were used for the test:  Claw, Herbal Avenger,
myBlur2, Stalker, Win!, Willow, Zoom, Origin of Storm.

And here are the scoring for eight different papers, having various length
decoys:

BR: Benji's Revenge;  D: Disincentive;  F: Fixed;  nP: nPaper II;
RP: Paper of Reepicheep;  RoP: Revenge of the Papers
MJ: Mini Return of the Jedimp;  RF: Return of Fugitive

The results weren't very surprising.  All paper gain a few points by having
a decoy.  Interesting is the inconsistency of the points increase depending
on the length of the decoy for the different papers.  If we look to the
average scores for the length of the decoy we can see more clearly that the
optimal decoy should have a length of at least 30 instructions.  The Q^3
should fit this length while the mini Q^4 is a bit too small to act
sucessfully as a decoy.


length Average  incr.
---------------------

70      139,8   3,2
80      140,1   3,5


Now let's have a look how well the quick-scanners alone scores against the
scanners.  Both quick-scanners start at the end of the scanning phase a djn
0, #200.  The quick-scanner will die after 200 additional cycles to be sure
all kills due the bombing are recorded.  The results shows as expected,
that the Q^3 scores much better than the mini Q^4.

  Q^3         42      15,6      18,7
 mQ^4         26      10,4      12,0


If we now use both quick-scanners together with the paper we get the
following results:


length    BR      D       F       nP     RP      RoP     MJ      RF
---------------------------------------------------------------------
Q^3     136,3   153,5   158,8   142,0   161,1   140,7   136,3   162,2
mQ^4    129,4   148,1   156,6   135,4   156,8   136,9   129,9   154,6

The points increase compared to the pure paper are shown below:

Q^3     10,3    11,9    9,9     8,5     8,5     19,8    13,1    15,9
mQ^4    3,4     6,5     7,6     1,9     4,1     16,1    6,8     8,4

Well, that's what we've expected after the tests with the quick-scanner.
The reason why the points increase isn't as high as expected from the tests
above can be explained with the delayed launching of the paper, because the
quick-scanner will executed first.  Interesting is the behaviour of
Revenge of the Paper, because it scores with both quick-scanners much
better than expected.  The reason seem to be that it only launches the two
copies of itself and don't use the code in front of the quick-scanner.

Finally we can say that a Q^3 quickscanner is the better choice if the
opponent is a scanner.  Against other strategies it can respond
differently.  But this can be discussed as well as the influence of booting
in a further article.

Extra Extra - unheard-of by Christian Schmidt

The last few months I have been engaged in improving papers carrying a
stone in their main body.  However, most of the ideas (including that one
already shown in the corewar lexicon) weren't effective enough against
modern scanner and oneshots.  The reason seemed to be mainly a
disadvantageous process allocation between self-replication and bombing.
The bombing run was way too slow to trouble scanners.  Therefore the first
and most important step in developing a successful "silk-stone" would be
finding a good process allocation.

My first idea was the use of an evolved-style paper.  It starts the self-
replication using a spl 0 instruction.  I thought this should push enough
processes into the stone.  But all my attempts were unsuccessful.  So, I
stopped this path and tried something much more simple.

I remembered "Minireturn of the Jedimp" with its bombing imp-launcher which
uses a spl #something right behind the spl/mov-silk.  Well, why not simply
add a dwarf right behind the spl/mov-silk.  It should act like a pure stone
with a steady deceleration of the self-replication.

So, I decided to use a 4-line stone with good bombing/corecolouring and
just
one constant, for ease of optimization.  Then I added a silk-pair in front
of it and voila, my first "silk-dwarf" was born:


        spl     2
        spl     1
        spl     1

silk1   spl     @0,             <pStep
        mov.i   }-1,            >-1
        spl     #sStep,         >-sStep
        mov     {sStep,         {-sStep+1
        add     -2,             -1
        djn.f   @0,             {-2


I have tested in the meantime several other types of stone, including
Carbonite-style stones, and I found that the above mentioned one is by far
the best.


Finally I added after optimizing pStep and sStep a quickscanner and named
it He Bombs Alone:

Wow, this isn't too bad.  It scores nicely against all carpet laying
scanners and loses only against Blur-style scanners and oneshots.
Important to mention is it shows surprisingly many wins against 'non-imp'
papers and stone/papers.  The bomb run seems fast enough to achieve more
than 50% wins against some of them, such as Disincentive and Fixed.  Really
impressive....

To get over the weakness against oneshots I included a further paper.  A
6-line imp paper which I had already optimized for "Fast Action".
Important is this case, is the fact both paper uses the same number of
parallel processes.  So, I then had to generate the processes just once.  I
added a mini Q^4 scanner and booted both papers away from the quickscanner.
After optimizing the boot-distances for an optimal interaction I had the
final code of unheard-of.
