%description
Most estimators implemented by the video game industry cannot obtain
reliable initial estimates nor guarantee comparability between distant
estimates. TrueSkill Through Time solves all these problems by modeling
the entire history of activities using a single Bayesian network allowing
the information to propagate correctly throughout the system. This
algorithm requires only a few iterations to converge, allowing millions of
observations to be analyzed using any low-end computer. The core ideas
implemented in this project were developed by Dangauthier P, Herbrich R,
Minka T, Graepel T (2007). "Trueskill through time: Revisiting the history
of chess." <https://dl.acm.org/doi/10.5555/2981562.2981605>.
