So I wrote a python script that runs through a given combat situation several thousand times and gives you simulated outcomes. I've had this working for a little while now and I think I'm satisfied enough to be willing to share outside of the
AM tactica thread.
You can find it at
https://github.com/daed/mathhammer, which is also in my sig.
Note that the work on this was mine, though the original credit for the idea belongs to our Inquisitor Lord Katherine who wrote his/her own first, though to the best of my knowledge, has not made the code public.
It requires python 3.6 or higher, which you can download from
https://www.python.org/downloads/.
My eventual goal is to be able to put it up on some webhosting somewhere, and perhaps render graphs with the results. I also have no timetable for this whatsoever.
