The International Corewar League
The International Corewar League uses a different (dynamic) league concept, which is quite similar to the ranking system used in Japanese professional sumo sport.
Every warrior fights 15 warriors on the league in a multi-round battle (typically 100-400 rounds). Depending on the result a victory or a defeat is declared. In case of a tie a victory is declared randomly. In case of 100% ties a defeat for both warriors is declared.
This means after fighting the 15 opponents the overall score can range between 15 victories (15 - 0) and 15 defeats (0 - 15). The higher the number of victories, the higher the warrior climbs up the league for the next run. The higher the number of defeats, the further the warrior drops down the league. No matter what the result is, it is most likely that on the next hill run the warriors have to face different opponents.
To limit the distance of two warriors fighting each other the International Corewar League is divided into several segments. Warriors can fight only within each segment. The names of the segments are mostly taken from Sumo:
1. Makuuchi -> Top of the International Corewar League
4. Sandanme -> Middle of the International Corewar League
8. Amasumo -> Bottom of the International Corewar League
Each segment contains 400 warriors except Maezumo and Amasumo which contain 600 or more (depending on the number of warriors).
All entries will enter the International Corewar League at the bottom facing the weakest warriors of the league. As higher they climb as stronger will be the opponents and depending on their strength they might be able to climb up to the top of the International Corewar League or will 'hit the wall' somewhere on the way to the top.
The entries are devided into the following classes:
94draft warriors without the pspace instructions stp and ldp
94draft warriors containing the pspace instructions stp and ldp
LP warriors optimized for max. processes of 8 containing the pspace instructions stp and ldp
LP warriors optimized for max. processes of 8 without the pspace instructions stp and ldp
Warriors for the 1.ICPC rules without the pspace instructions stp and ldp
Warriors for the 1.ICPC rules containing the pspace instructions stp and ldp
PS: Sorry for the inconsistencies in the naming. Everything was organic growing over the past years.
All following special rules will give all entry
classes almost equal chances to be on top of the
International Corewar League.
Special rules for max. process
The max. process -p setting depends on which categories
battle each other.
Here is the matrix for the -p settings:
94/PW/88 DS/DN lp/ln NW
94/PW/88 High Mid2 Mid1 High
DS/DN Mid2 Mid2 Low Mid2
lp/ln Mid1 Low Lp Mid1
NW High Mid2 Mid1 Low
High: -p randomly for every battle between 8000 and 2000
Mid2: -p randomly for every battle between 400 and 120
Mid1: -p randomly for every battle between 160 and 80
Low: -p randomly for every battle between 120 and 16
Lp: -p fixed for every battle at 8
Special rules for warrior lengths
The maximum length for the warriors is 200. That one
for Nano warriors is 5
Special rules for '88 warriors
Compared to ICWS '94 the ICWS '88 instruction set is
limited. To give them an equal chance '88 warriors will
get therefor a special bonus.
- '88 warriors will get by default additionally 5-15%
of the rounds as wins.
- '88 warriors will get additionally 5-15% more wins
than they achieved in a battle.
Special rules for Nano warriors
Nano warriors fight each other in a coresize of 80
with the above mentioned max. process settings.
If Nano warriors battle a warrrior from a different
category distinct numbers of copies of the Nano
warrior are loaded into the coresize 8000 for a
For half of the rounds 6 copies of the Nano warrior
are loaded, for the other half 15 copies are loaded.
(This gave so far the most promising results)
The Nano warrior wins if the coresize 8000 warrior is
terminated. The coresize 8000 warrior wins if all
Nano warriors in the multi-battle are terminated.
- The predefined variable CORESIZE is allowed for
all warriors to calculate constants. This might
be useful especially for Nano warriors.
- The predifined variable CURLINE is allowed for
all warriors to calculate constants.
- All other predefined variable are disallowed.
- All warriors submitted will be automatically published.
- All entries must run properly with exmars and pmars.
- It is disallowed to use one of the pool warriors as
an entry. The md5 checksum of the compiled entries
will be compared with that one for the pool warriors.
How to submit to the International Corewar League
Format your submission as follows:
;redcode <- define the entry category

Submit your entries to: fizmo (at) corewar (.) info with the subject line: ICL
Although the International Corewar League itself runs fully automated, it didn't contain an e-mail daemon so far. This means that I have to copy the entry manually into International Corewar League and you might not get an immediate reply to your submissions.
