"You're not still mad about that nano hill thing are you?"
- BARKLEY VOWK, private communication (02 July 2007)
"nano is surprisingly brutal for such a small hill."
- MIZCU, irc.koth.org (09 September 2008)
The balance of power has changed on the nano hill. Scanners once ruled
the hill, now they struggle to find a niche. Paper once lurked in the
background, now it's slowly taking over.
In this issue we investigate the interaction between different strategies
on the nano hill and take an in depth look at nano paper. Along the way,
we discover some of the fundamental laws of Corewar do not apply to the
nano hill.

Exploring the Dynamics of the Corewar Nano Hill by John Metcalf
The History of the Nano Hill
----------------------------
To understand the balance of the nano hill, it's important to look how
the hill evolved over time. The early hill quickly became dominated by
two strategies, evolved streams and clears. The streams held a slight
advantage.
Next to make an impression were the scanners, oneshots and quickscanners.
They scored well against clears, but lost points to evolved streams.
Clears were losing on all fronts and started to fall from the hill.
Clears were soon replaced by clear/imps at the expense of the scanners.
Scanner/imps appeared, but too late - scanners would never again dominate
the nano hill.
All this time papers had been lurking in the background. They'd always
achieved reasonable scores, but they didn't have an opportunity to expand
their presence until scanners appeared. The number of papers on the hill
began to slowly creep up.
When imp rings arrived, they entered a hill ruled by streams and carved
their own niche. Scanners suffered further losses. Finally, paper/clear
arrived, claiming a strong position on the hill.
Nano Hill Score Matrix
----------------------
To further investigate how the strategies interact on the nano hill,
I took up to 10 representatives of each and entered them into a round
robin tournament. The scores have been grouped by strategy:
| pclr str pap cimp impr clr simp qsc shot scan stn | avg
-----+--------------------------------------------------------+------
pclr | 134 144 146 145 138 150 142 208 207 211 197 | 165.6

Key
---
pclr = paper/clear, e.g. "the spiders crept"
str = evolved streams, e.g. "Foggy Maus (beta)"
pap = paper, e.g. "ripples in space-time"
cimp = clear/imp, e.g. "the kraken awakes"
impr = imp rings, e.g. "legend of the ice dragons"
clr = clear, e.g. "around the core in 80 cycles"
simp = scanner/imp, e.g. "Xinyl"
qsc = quick-scanner, e.g. "wreath of thistles"
shot = oneshot, e.g. "victim of the night"
scan = scanner, e.g. "girl from the underworld"
stn = stone, e.g. "nano nano mork calling orson"
Performance
-----------
Paper/clear beats every class of opponent. If an ultimate warrior is
ever discovered for the nano hill, chances are it'll be a paper/clear.
Both paper/clear and paper receive impressive scores against scanners.
Paper/clear has a slight advantage over paper.
Evolved streams (a.k.a. mad mad bombers) beat almost every strategy -
imp rings being their one weakness. Evolved streams typically score
better against non-scanning opponents than any other class.
Clears have mediocre performance, not achieving a strong score against
any strategy. Their greatest weakness is versus scanner/imps. Adding
an imp improves the score against scanners, but weakens the score
against other strategies.
Imp rings score well against scanners and fairly well against evolved
streams and clears. Their score against paper/clear and clear/imp is
poor.
Scanners, oneshots, quick-scanners and scanner/imps generally have poor
scores against most strategies. However, they receive reasonable scores
from evolved streams and clears. Scanner/imps have a slight advantage
against other types of scanner.
The Future of the Nano Hill
---------------------------
Paper/clear and evolved streams will soon dominate the nano hill. A
small number of papers will remain on the hill. A few imprings, clears
and clear/imps will come and go as the balance of the hill changes.
That is, until the next big discovery to shake up nano...
_____________________________________________________________________________
Strategy: Paper/Clear on the Nano Hill by German Labarga
After lurking in the background since the beginning of the nano hill, paper
took advantage of the abundant presence of scanners and finally showed up
on the nano hill in numbers, taking a strong position alongside the evolved
clears. On the nano hill, paper beats scanner.
Lets see how these creatures have found their way onto the hill.
The classic silk structure barely fit into the extremely reduced size of the
nano settings and against most opponents becomes damaged before spreading
properly.
Using copy loops like limited process paper faces similar problems.
A third method was also tested early on with limited success, but this was
the seed for modern nano papers.
The idea was to use the same method seen in evolved papers on bigger hills.
That is to make the copy in a self-splitting loop, which finally jumps to
the copy instead of closing the loop.
"More mutated beast" used a spl instruction to activate the copy while the
copy loop acts as a clear.
;redcode-nano
;name More mutated beast
;author Neo
;assert CORESIZE==80
;strategy 5-line evolved-style clearing paper
dest equ 24
start: spl #0,<-5
spl dest,<-1
mov.i }-2,}-1
mov.i }-3,}-2
djn.f -2,<-15
end start
Despite some early failures, this strategy would later show its
effectiveness.
Fluffy's Black Sun III is a typical evolved paper that works as described
above. We can say it is simply a clear wich has evolved to make a copy of
itself and send processes to the copy. It remained on the hill for a few
days.
;redcode-nano verbose

mov.i } 79, > 79
mov.i < 73, < 37
mov.i < 36, < 72
djn.i } 18, < 49
END
The door was open for the next generation of papers. Actually nano papers
are already paper/clear, copying and clearing in the same loop. There
are two main variants.
"ripples in space-time", whose optimization is explained later in this
issue, activates the copy via the final DJN instruction, (comments added):
;redcode-nano
;name ripples in space-time
;author S.Fernandes
;strategy paper
;assert CORESIZE == 80
pstep equ -17
ipos equ 10
cpos equ -33

mov >ipos , -16 ; <--- split to copy
clr: mov * 31, < -8 ; <--- clear
djn.f $ clr, < 46 ; <--- djn trail and loop to clear
end
Notice in the first variant the processes are sent to the SPL head of the
copy, seriously increasing the number of processes and slowing down the
paper. This one creates new processes and sends them all along the copy.
Once the copy is completed newly created processes die on empty core, thus
making the SPL useless. Though this could be seen as a means to increase
its life expectancy by executing opponent code or other paper copies. The
first seems to be more a robust and compact code while the second spreads
faster and looks more aggressive.
Lets compare a few of these papers with a benchmark.

listen to the rain, Black sun III, Nano'Powa and Wall of spikes all use the
first paper variant and get the fastest results, though both variants show
their effectiveness with the most modern papers coming out on top. All
papers had more average wins than losses.
And now a round-robin with all the papers:

When it's about facing other papers, things change a bit, but most modern
paper/clear give good results. Their aggressiveness is clear, showing
quite a low tie rate for a paper. The only silk appears at the bottom in
both tests.
More detailed results are available on demand.
The code of all the warriors used in this test has been made public.

Optimizing Ripples in Space-Time by S.Fernandes
While looking through the breakdown of nano warriors by strategy I
noticed the absence of a decent 4 line paper, despite the success of
5-liners like Fluffy's Black Sun III. I quickly hacked something up
and added a quick-bomb to the beginning.
I tested with some hand-picked constants against Metcalf's nano
benchmark. It scored 139.2, or 129.8 with the quick-bomb removed.
