This function computes logit agent quantal response equilibria using the Gambit solver gambit-logit. For a short description see the Wikipedia article and the gambit-logit solver's https://gambitproject.readthedocs.io/en/latest/tools.html#gambit-logit-compute-quantal-response-equilbria. Details are in the article https://link.springer.com/article/10.1007/s00199-009-0443-3 by Theodore Turocy. But unfortunately, the article can only be found behind a pay wall.
