Python Trueskill (ELO) scores drift down

Creating an specific kind of tuple from a dictionary (python)

QUESTION

Python Trueskill (ELO) scores drift down

Asked 2017-Dec-01 at 23:41

why is it that a random population with random winners, the scores slowly drift to 0. I get that the scores might be random, but why always drift negatively?

You're using the TrueSkill algorithm, not ELO. TrueSkill has a different method for updating skill ratings. While ELO is a zero-sum system, TrueSkill relies on an uncertainty parameter (determined by by both the number of games as well as their outcomes) to adjust skill ratings. Therefore, TrueSkill is only zero-sum if the two players in a match have equal uncertainty values.

The simulation you ran creates situations where players will have vastly different uncertainty parameters. This, coupled with the fact that you are violating the assumption that higher rated players will win more often, will result in some strange behavior. A better simulation would be to have several round-robin schedules. This way the amount of games played will be more similar in every matchup. If you run the code below, the average rating will stay close to 25.

First of all, I'm very new to programming. (this is my second question here in the overflow.)

I've been studying for almost 6 hours. I've read a lot here in stackoverflow and many others python websites. Most of my doubts were gone and now I got one I couldn't really solve.

Look, I have this simple dict:
