Fictitious Play (Baseline) (Lech Mazur baseline strategy)

Lech Mazur Benchmarks

Fictitious Play is an algorithmic baseline in Lech Mazur's BAZAAR double-auction benchmark. The official repository says it assumes opponents draw prices from a fixed but unknown distribution, builds a frequency distribution from all past opponent quotes, and best-responds to that belief; published game logs use `fictitious` as its non-LLM `model_name`.
