January Challenge Results
First of all, this challenge saw the achievement of a great result: After 13 months of victories, KillerBees failed to win at least in one type of play. This result needed a lot of efforts, but it's not the end of a hard struggle, in fact there are rumors of a KillerBees2 waiting for the end of KillerBees. Are we going to see it appearing in the next challenge?
Then, for the first time in the history of Jrobots there was something offered as a prize to the winners of the three categories. It is a very symbolic prize: A complete set of EURO coins for a total amount of 388 eurocents. It's the first time that several countries adopt the same currency with one accord, so I thought that even Jrobots ought to celebrate the event. I hope that the winners will appreciate the prize.
As you can see from the placement list, the winners are Zeke (author of IonStorm - winner in single and double categories) and chestRcopRpot (author of OneEyedWilly - winner in team category). Zeke decided to transfer one of his two prizes to WalterNistico (author of KillerBees) in honour of KillerBees' valour and I'm planning to give another prize to Critter (the author of Germ - second placed in team category) because he lacked the victory for 7 matches lost over more than 700, really near to a surprising OneEyedWilly.
The weighted selection strategy seems to work well, surely better than random selection and bubble-sort placements selection. As you can see, the first robots in the placement list has more probability to play a match. This choice improves the winning percentage of the best robots and the reliableness of the results.
IonStorm won in single mode with its usual percentage above 80% and in double mode it beated KillerBees with a gap of 4%. OneEyedWilly won in team mode and repeated the exploit it already made in October 2001. Its performances are not so regular and Germ is so near to it that I can't say which of the two is the strongest in a weighted challenge. The test I've made on my machine says that Germ is stronger than OneEyedWilly, but the machine dependency of Jrobots is unpredictable. We'll see what's going to happen in the next challenge.
From the novices' side, there were a lot of new challengers, but none of them survived. The best of them was FuzzFighter. With two victories in team play it could reach the 25% limit and survive, but I'm sure that teofuzz (author of FuzzFighter) has already a stronger version ready to be uploaded.
Finally, someone asked me why Leech and DirtyCoward performed so bad in this challenge. Well, I had an idea for new good tune-ups, but they reveled themselves not so good. Next time I'll be more conservative :)
The robots fought a total amount of 16076 battles. To see the results read the Challenges page.
Here is an abstract:
|Single Winner||IonStorm||by Zeke||82.14%|
|Double Winner||IonStorm||by Zeke||77.12%|
|Team Winner||OneEyedWilly||by chestRcopRpot||56.65%|
Now you can upload your robots to win the February 2002 Jrobots Challenge (February 2nd-23rd 2002) aka No More KillerBees?
