Sun, 09 Aug 2015 21:54:25 GMTI have two combatants, A and B. Each has three stats (X,Y,Z). Each round of combat, they make three choices, and roll a random value. All of this determines the outcome of the battle, which can be a win for A, a win for B, or a tie. I know the attributes of A, and want to work out the attributes of B given that I want A to win N% of the time. Right now my method for doing this is to pick starting values for B's stats, then run 10,000 simulations in which the three choices by both combatants are (mostly) random each round and figuring out what the odds of A winning are, then changing the stats of B and trying again, narrowing in on the wanted odds of winning. Needless to say, that's going to take a long time, especially as all of those bits (the three stats, the three choices) are independent of one another. I have, however, run a large number of such 10,000 trial simulations with various stats at X, Y, and Z compared to a fixed competitor (randomly selecting the three choices each round for both and randomly rolling) to see how often wins and ties happen. Can I use this to somehow work out a way to calculate the three stats involved instead of running dozens of simulations to see what happens?

EDIT: I can provide more details about how the combat works if that would be helpful to finding a better solution.

Wed, 05 Aug 2015 05:35:32 GMTI have this actual picture with size width and height at 14x17 inches. In px @ 96 dpi, that is 1344x1632 then multiplied it by 35% and that is 470.4px x 571.2px for my fixed size of my image element.
Now I have this new picture with size 8 x 10 inches In px @ 96 dpi, that is 768x960. But I have a fixed sized of 470.4px x 571.2px for width and height.
Now I want to know what is the percentage of zoom factor where I can say that when I multiply 768 and 960, the result will be 470.40 and 571.20.
Maybe you will advice me, to divide 470.40 by 768 and 571.20 by 960, then add the result and divide that by 2 to get the average zoom factor. But I am not sure if that is the right computation.I have this actual picture with size width and height at 14x17 inches.
