CoreWar "Koenigstuhl" Page


This hill is named after the location of the place where I worked (Max-Planck-Institute for Astronomy) until 1997 ('Koenigstuhl' translates to 'King's Chair'). Similar to Planar's Mt.Olympus (last update: 1998-08-31) this is an infinite hill. The difference is that I separated the hill into several categories and I let every program fight every other program:

Standard Hills (CORESIZE==8000)
  • 88 ('88 instruction set)
  • TOP-50: Top 50 of the 88-Koenigstuhl
  • 94nop ('94 instruction set, no Pspace, no '88 programs)
  • TOP-50: Top 50 of the 94nop-Koenigstuhl
  • Pspace (Pspace-only)
  • TOP-50: Top 50 of the Pspace-Koenigstuhl
    Classical Hill ('88 instruction set)
  • ICWS/64 (CORESIZE==8192 && MAXPROCESSES==64)
  • ICWS (CORESIZE==8192 && MAXPROCESSES==8000)
  • Other Hills (94draft instruction set)
  • Limited Process (MAXPROCESSES==8 && MAXLEN==200)
  • X (CORESIZE==55440 && MAXLEN==200 && MAXCYC==500000)
  • Tiny (CORESIZE==800 && MAXLEN==20 && MAXCYC==8000)
  • Nano (CORESIZE==80 && MAXLEN==5 && MAXCYC==800)
  • Odd Hill (non-competitive, special tournament rule sets)

  • '88 hill(s): "-8 -r 1000" (663 entries: 88.tar.gz)

    Recursive 88-Koenigstuhl -- Battle Royale 88-Koenigstuhl

    Recent entries: (rank on recursive 88-Hill, program, author, date-of-entry)

    14: Stasis Prime , inversed, (Jan/13)

  • 88-TOP-50 Hill, "-8 -P", '88 rules (15602 rounds)

    Any program that reaches rank-50 or higher on the '88-Koenigstuhl will also enter the TOP-50 Koenigstuhl. Programs that fall below rank-50 on both ('88 and TOP-50) hills will be removed from the TOP-50 Koenigstuhl.

  • 94nop-TOP-50 Hill, "-P", 94nop rules (15602 rounds)

    Any program that reaches rank-50 or higher on the 94nop Koenigstuhl will also enter the TOP-50 Koenigstuhl. Programs that fall below rank-50 on both (94nop and TOP-50) hills will be removed from the TOP-50 Koenigstuhl.

  • Pspace-hill(s), "-r 1000", Pspace ok (206 entries: pspace.tar.gz)

    Recursive Pspace-Koenigstuhl -- Battle Royale Pspace-Koenigstuhl

    Note: "-P" (randomizing all possible starting positions) will not make the battles reproducible, because the order of the fights makes a difference with P-space.

    Recent entries: (rank on recursive Pspace-Hill, program, author, date-of-entry)

  • Pspace-TOP-50 Hill, "-P", Pspace ok (15602 rounds)

    Any program that reaches rank-50 or higher on the "full" hill will also enter the TOP-50 hill. Programs that fall below rank-50 on both hills will be removed from the TOP-50 Koenigstuhl.

    Recursive X-Koenigstuhl

    I switched to pmars-0.9.4 and a 32-bit (little endian) score table (was 16-bit and pmars-0.9.2).
    Please note that I did not create a Battle Royale hill, since running all permutations (-P switch) on the 'X' hill would take quite some time; maybe later ...

    If you cannot find your program(s) here, please send your program to ccbirk AT gmail DOT com with a subject line like 'Koenigstuhl entry'. Please note that the Koenigstuhl is an "archive" hill, ie. published programs only. If you would like to see how your program would do on the Koenigstuhl before you publish it, please download the appropriate hill and run your program against it.
