Jrobots Challenges
[2008] [2007] [2006] [2005] [2004] [2003] [2002] [2001] [2000]
NEXT CHALLENGE
May 2008 JROBOTS Challenge (May 3rd-31st 2008)
aka Veterans' 13!
Rules
The challenge will start on May 3rd (at about 3 PM GMT): the statistics will be reset and the robots will fight to win the May 2008 JROBOTS Challenge.
During the challenge you can update your old robots (in both Veterans' and Cadets' League) and even send new robots in the Cadet's League.
The challenge will end on May 31st (at about 3 PM GMT).
The matches are chosen by the Battle Applet using a weighted algorithm: every time a match ends, the applet computes the placing list; in the next match the first robot is chosen with a probability proportional to its percentage, then the others robots (one for single and bouble, three for team play) are chosen with a probability proportional to the difference of their overall victory percentages (read the January 2002 NEWS for details about this new selection strategy).
At the end one or more robots will have the largest number of matches played, say N. The winners of the three categories will be the robots with the best victories/matches percentage and at least N/4 matches played.
In the Veterans' League, the robots below the 50% in Single and Double play and below the 25% in Team play (first four placed apart) will be degraded to Cadets.
In the Cadets' League, the robots above 50% in Single or Double play or above 25% in Team play (at least two must fit - except when the negative category is in the demotion area) will be promoted to Veterans, while the robots below the 25% in Single or Double play or below the 12.5% in Team play (at least two must fit - first four placed apart - except when the positive category is in the promotion area) will be removed from the arena.
The name of the winning robots will be recorded in the Jrobots Challenges Hall of Fame (here).
Good Luck!

Comments
This month the tournament haven't shown much movement. Only the veterans succeeded in collecting enough matches, while the cadets' ones are too few to consider the results reliable. Thus the cadets need to wait another month before deserving a promotion.
The Tinker vs Grappelli fight has given again the same winner: Tinker. Now it confirmed its valor and survived for the second time among the veterans with an interesting 5th place in team category.
The survivors among the veterans are: Tango (3-1-3), Spike (1-6-2), StrangeMatter (2-3-1), IonStorm (4-4-4), Starkle (5-2-7), Headhunter, HellFire, TTL (6-5-6), Tinker (11-11-5), DOOM (7-8-8), Mouth (10-10-9), Bohan, GulleFjun.
The demoted veterans are: DarkSoldier, AronsRobot02, Berserk, Jimbo, 845bytes, MarukoV4, Singularity, Errata, Grappelli, Hal9000, Bosozoku, Janeway, Teddybear.
The May Challenge will see a Cadets' League very crowded, while the Veterans' 13 will fight for supremacy.
Now you can upload your jrobots to win the May 2008 JROBOTS Challenge (May 3rd-31st 2008) aka Veterans' 13!
