我们提供了一种具有恒定运行时间的算法,给定加权锦标赛 T,以高成功概率区分 T 可以用 Bradley-Terry 模型表示的情况,或者甚至不能用一个模型来近似的情况。同样的算法测试相应的马尔可夫链是否可逆。
We provide an algorithm with constant running time that given a weighted tournament T, distinguishes with high probability of success between the cases that T can be represented by a Bradley–Terry model, or cannot even be approximated by one. The same algorithm tests whether the corresponding Markov chain is reversible.
