x amount / amout of bots in melee = delta
nfi if that would work cause i aint no mathamatition or literature expert for that matter as you can see but it looks good to me care to test this out?
Nope that won't work. If you win a melee you'll get over 1000 points. Considering Sorry is less then 400 points ahead of the worst robot it won't be a very fair system.
Actually I've been playing around with this method for dealing with melee's:
-Find the average points for the loosing robots (and for the winners if there were more then one such as in an annihilator fight).
-Instead of using 27 for K as in the one-on-one fights use
K = (number of robots in melee x 2) + 23
That way winning is worth more if there are more robots in the fight.
-So delta = (average of the loosers * K)/average of the winners
-The winners new score = the old score + (delta/the number of winners)
-The loosers new score = the old score - (delta/the number of loosers)
This way if there are a lot of robots in the fight and you loose, you loose less points from your score then if there were less robots in the fight. This makes sence because you have less chance of winning a 10 way melee over a 3 way melee. So you should be penalised more for loosing a 3 way. But you'll still loose less point then if you lost a 1-on1 fight. Also if you win a 10 way fight you get (roughly) 43 points, a 3 way would give you (roughly) 29 points and a 1-on-1 gives you (roughly) 27 points.
I tested it out on Metal Mayhem 1 which had 3 melees.
Melee 1 (Haemorrhage, Annihilation, Hellbringer and Spiney Tiger)
Haemorrhage - 1231
Annihilation - 1189.66667
Hellbringer - 1189.66667
Spiney Tiger - 1189.66667
Melee 2 (Annihilation, Hellbringer, Spiney Tiger, C4 and Frogg Stomp)
Annihilation - 1222.80999
C4 - 1191.71417
Frogg Stomp - 1191.71417
Hellbringer - 1181.38084
Spiney Tiger - 1181.38084
Melee 3 (Hellbringer, Annihilation, Spiney Tiger)
Hellbringer - 1210.88933
Annihilation - 1208.05575
Spiney Tiger - 1166.62660
See Annihilation got penalised more for loosing the 3 way then Hellbringer did by loosing the 5-way. But it still won more points from the 5-way the Hellbringer did.
Any comments would be helpful. _________________ Get Some!!!
