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:

  • 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.

    "Flat" Scores:
    On each hill a new challanger fights a N-round battle against every programs (different from Mt.Olympus) already on the hill. The result of this battle changes the score for both opponents:

    For the programs already on the hill:
    new_score = {old_score * (#hill-1) + score_against_challenger} / #hill
    For the 'challenger':
    score = (score1 + score2 + ...) / (#hill)
    After doing all battles for a new challenger I re-order the hill and write the new hill-page(s).

    "Recursive" Scores:
    Current: The recursive algorigthm weights scores against better programs more and calculates a new hill from the data provided by the "flat" hill. This procedure is repeated (with decreasing absolute weights) until a stable hill is reached (or a cut-off of 25 programs is reached).

    Maybe in the future? The recursive algorighm starts with the round-robin (flat) scores of the entire hill. The bottom half is fixed in place, then the top half is re-evaluated only within itself. This process is repeated until the top part reaches a cut-off size of 50 programs.

    If you cannot find your program(s) here, please send your program to birk AT carnegiescience DOT edu 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.
