When rolling 8 to 8, i lost my 11 attacks and my enemy had neary %50 ratio a few months ago. I ignored the case. But i played and played, that it sometimes happen again and again. I really suspecious about the dice rolling algorithm for n vs n case.
1) Is it pure random or is there some other factors that are taken into account (i.e. colour of neighbours(ally or opponent) of attacking cell, etc.) 2) Do you choose randomization seed one per player or totally 1 seed for all players? |

The math / reasoning in that artical is incorrect. The probability of loosing (or winning) x or more consecutive 8v8's in y attacks is p = (y - x + 2) / (2^[x+1]) assuming a 50% win / loss chance. (yes I was bored). Generally only 2 players will get the chance to make enough 8v8 attacks for this issue to arrise, so the probability of an 'unusual event' occuring in a given game is p_unusual = 1 - (1-p)^2. The probability of such an event occuring in 100 games is p_100 = 1 - (1-p_unusual)^100. Setting x to 12 and y to 40 (an unusual event is thus getting 12 or more consecutive losses (or wins) in 40 8v8's), p_unusual = 0.73% and p_100 = 0.52% i.e., there is a 50% chance u will see one or more people royally screwed in every 100 games u play. Seams reasonable enough... |

at 1:32 PM, Thursday October 18, 2007 EDT I'm fixing up this part of the site at the moment, (stats/forum/ideas), and have added a new stat that measures your luck. So even if you get some bad luck at least you know. :)
