Core Warrior is a newsletter promoting the game of corewar. Emphasis is placed
on the most active hills - currently the '94 draft hill, the beginner hill and
the '94 no-pspace hill. Coverage will follow where ever the action is. If you
haven't a clue what I'm talking about then check out these five-star internet
locals for more information:

Welcome...

There has been very little activity either on the hills or in the newsgroup
since last issue. However, Ian Oversby's tournament has reached a conclusion,
with someone winning a copy of Ian's paper/stone, Recovery. Also, Macrae won
the code for Mini-CLP by solving Kline's Challenge.

This issue, Christian Schmidt shows us how he constructed and optimized three
of his multi-strategy warriors, Digital Dragon, Shadow and Stormbringer :-)

Age since last issue: 10 ( 69 last issue, 33 the issue before )
New warriors: 11  Turnover/age rate 110%
Average age: 8 ( 3 last issue, 46 the issue before )
Average score: 138 ( 143 last issue, 140 the issue before )
The top 25 warriors are represented by just 10 independent authors: Metcalf
with 7, Schmidt with 5, Moore with 3, Ford, Gunnell and Humberto with 2 each
and everyone else with just one warrior.

Fixed, Pattel's Virus and Spooky Wench each had a short time as King before
Recycled Bits claimed top spot. Still we have 10 warriors of the same age,
down from 20 last issue.

15 successful challenges since last issue, and only Scanzonato perished of
old age. The top five comprises a good cross-section of strategy: 2 p-space,
a scanner, a paper and a bomber. Beginners might like to try submitting
warriors to one or two of the alternative hills, which are easier to enter
than you may think.

The no-pspace hill has aged by 40 successful challenges this month, with
scanners now ruling the hill once again. Gemini Dream left the hill aged
182 and Fugitive becomes the oldest warrior. Centenarians Head or Tail,
Floody River and Red Carpet also departed. 16 of the 20 warriors on this
hill use some form of Qscan.

The Hint -
Optimizing Process Allocation in Parallel-Running Strategies
by Christian Schmidt

In this month's hint I would like to present a little known method to
optimize warriors with two parallel-running strategies.  For example,
stone/papers, stone/imps and clear/imps.  Everyone who has tried to
build a stone/imp knows that one of the most important decisions is how
long the spiral should be allowed to grow.  With weak imps the fast
running stone will easily beat a scanner, but will lose badly against an
agressive paper.  With strong imps the warrior will tie against paper,
but due to the slowed down stone it loses against anti-imp scanners.

A good stone/imp is somewhere between these extremes.  The most common
ways to keep control over the time the imp spiral grows are:

a) the use of a fixed number of processes for the imp, as would be
   created by a jmp/add, vector or binary launcher,

b) to kill a continuous-imp launcher with a dat-bomb from the stone at a
   fixed time,

c) to delay the start of a continuous-imp launcher until a self-
   splitting stone has build up enough processes.

In all three methods the goal is to slow down and weaken the imp, so the
stone runs faster.  However, there is another possiblility.  Instead of
slowing down the imp, speed up the stone.  Accelerate the stone by
launching multiple processes into it.

As far as I know the first example of this technique involved in a
stone/imp was Alien and in a clear/imp Justin Kao's Dust 0.7 and later
Digitalis.  In all cases the add/jmp-launcher starts both, the imp and
the stone (Alien) or the d-clear (Dust, Digitalis).  To introduce the
faster and smaller continuous-imp launcher into this warriors the stone
(or clear) must now launch separatly.  Instead of a:

    jmp    stone    ;----> 1 process for the stone

it could be used for example:

    spl    stone
    jmp    stone    ;----> 2 processes for the stone

or maybe:

    spl    2
    spl    stone
    jmp    stone    ;----> 3 processes for the stone

Every combination is possible.  One advatage is the relatively easy
optimization of the ratio of processes in the stone and imp.  An
additional acceleration of the stone is possible by using a spl #0
instruction in front of it.  This helps gain a lot of extra points...
All of the discussed improvements are used for The Stormbringer, where
the stone is Carbonite.  The big advantage against other stone/imps is,
that it is very small and extremly fast.  The only disadvantage is that
there is no real core-clear at the end of the bombing phase.

Using exactly the same method I created Digital Dragon (everybody will
see the similarity to The Stormbringer ;-) with a d-clear.  But instead
of the 3pt imps I used here 13pt imp.  I've used this because it gave
the best results on the hill.  Though it isn't as lethal as Digitalis 4,
it loses much less against q^2 -> papers due to it's smaller size and
faster launching.

Finally, with this method it is now also possible to combine a stone
with a paper, in such a way, the stone dominates in the beginning until
the paper becomes dominant.  The first task is to find a 'pocket' for
the stone, where it survives the paper until close to the end of the
battle.  To do this, run the paper alone and seach core to find the
location of pockets of initial core.  Now you must check in which of the
pocket the stone will gain the most points, and what ratio of processes
the stone needs.  I found that the easiest way is to launch the stone is
with the paper launcher.  For Shadow I've used Paul Kline's RetinA,
which gave by far the best results.  Shape used for example my paper
from Head or Tail.
