The current event is the...

The first-quarter Challenge of 2009 (2K9Q1) made a great selection between the veterans. Only six of them survived and will fight one against the others for the next three months: TTL (6-5-6), Starkle (5-4-5), IonStorm (4-3-4), StrangeMatter (3-2-3), Spike (2-6-1) and Tango (1-1-2). All the others were demoted to cadets: GulleFjun, KillJoy, Mouth, Bohan, Tinker, KillerBees, Stately, HellFire, DOOM, Headhunter. They are going to have fun among the cadets, but also some of them will fail to be promoted again.
Among the cadets nothing interesting happened because the matches played were too few to be considered significative.

The January-March Challenge ends now! The official results will be available on Saturday, April 4^th 2009, please be patient!
The next tournament will be the April-June 2009 JROBOTS Challenge (April 4^th-June 27^th 2009) aka JROBOTS 2K9 Q2!

The final Challenge of 2008 was very poor in matches for what regards the Cadets' League, in fact no new jrobots were uploaded and the only three appeared in the arena were copies of the sample jrobots included in the SDK (Simple, Rook, Sniper). Of course, I removed them from the arena for their poor results and no other jrobots was promoted because the number of matches is too low to consider the percentages reliable.
In the Veterans' League, the usual struggle between the stronger jrobots has given a few results different from the usual ones, but the final outcome is more or less the same as in the past challenges.
Among the veterans the results are:

• Survivors: GulleFjun, Mouth, Bohan, KillerBees, (for their results in team category) KillJoy, (for its result in double category) Tinker, (for its result in double and team category) Hellfire, Headhunter, (for their results in single and double category) DOOM (10-12-8), Stately (9-19-11), TTL (6-5-6), IonStorm (5-2-4), StrangeMatter (4-3-3), Starkle (3-4-10), Spike (2-7-1), Tango (1-1-2).
• Demoted: Vampire, AronsRobot02, MarukoV4, Dragon, FlameBall, Grappelli, Butterfly, RoboOlm, Earthworm.

The November-December Challenge ends now! The official results will be available on Saturday, January 3^rd 2009, please be patient!
The next tournament will be the January-February 2009 JROBOTS Challenge (January 3^rd-February 21^st 2009) aka JROBOTS 2K9!

The end of the September-October Challenge does not show many new jrobots. The only one were Ulisses and S (yes, just an "S"). The first was removed because of its poor results, the second did not achieve the requested percentages to be promoted.
In the Veterans' League the stronger jrobots are always the same (even if most of them has not been improved for years). This testifies that the virtual-clock generator smooths the hardware advancements giving reliable results even after so many years of challenges.
Then, in the Cadets' League we can see the usual struggle among strong jrobots that fail to survive long enough in the Veterans' League. I'm sure that they need only a few improvements in their strategies to be much more effective.
The Cadets' League results are:

• Promoted: AronsRobots02, MarukoV4, Vampire, Dragon, Grappelli, Butterfly, KillJoy, Earthworm, Mouth, Stately.
• Survivors: Touche, GenuineA, Shark, Nemesis, RoboScape, Genuine, Ender, S, AronsRobot01, DirtyCoward, DeathIncarnate, Snutteplutt, Yoda, EvilElmo, Shrike, DeadDuck, CounterStrike, Singularity, Bizarro.
• Removed: Ulisses.

• Survivors: GulleFjun (T), Tinker (DT), FlameBall (T), KillerBees (D), Bohan, DOOM, RoboOlm (ST), Headhunter (SD), HellFire (SD), TTL, StrangeMatter (5-3-5), IonStorm (4-2-4) Starkle (3-6-3), Spike (2-4-1), Tango (1-1-2).
• Demoted: Berserk, DarkSoldier, LadyBug, RatBot, Jimbo, Errata, Bosozoku, 845bytes, Janeway, Teddybear, Hal9000.
