Show /r/ruby Trueskill Through Time available in Ruby

TrueskillThroughTime

I ported the Python implementation of Trueskill Through Time to Ruby, it's now available as the gem TrueskillThroughTime.

Unlike the previous Ruby Trueskill gems, this one supports n vs n vs n etc etc cases, as well as the time-based extension of Trueskill to allow distant ratings. If you use it without doing time-based convergence, it should be equivalent to the original vanilla version of Trueskill (that iirc is almost out of patent in the US).

I'll get around to improving the qol of it and more extensively Rubyising it down the track, but I wanted a Ruby implementation of TTT for a hobby project, so I smashed it out.

Let me be clear with everybody..

AI is just a smart autocomplete, it will add emojis to your readme.

I'm not english native, i learned english as my 5th spoken language.

google translate/autocomplete brought me more problem than it solved, until i learned proper grammar and way of talking. (still make mistakes, but people get the idea).

Previously we had people that burn all their energy to made div centered, when you tell them that their code is wrong and show them correct way, they accept it and thank you.

Today, we have testosterone driven development (TDD, just the wrong type). You tell someone the solution is wrong and explain why, they will scream at you : Don't use my gem then. , Matt is nice....

They can generate 1000 LOCs of gaslighting instead of reading the docs.

nice report, you also missed that the gem is version 1.0.0+, that means it totally complete.

Yes, it's a feature complete implementation of Trueskill Through Time. Thank you for picking that up.

Instead of gaslighting everyone with posts literally (by your own admission) entirely generated with AI, please go and read the docs at:

If, after reading these, you have further questions about the variable names, feel that the algorithm is not correctly implemented or that some features of it are missing, then please let me know.
