Bidder CDF comparison. (a) shows the CDFs for each of five different auction designs assuming the bidder plays the Nash distribution. The first prize is listed in the legend; the second prize equals one minus the first; no prize is given to the third bidder. The remaining plots compare the Nash CDF with the CDF learned by Fictitious Self-Play for different first prize amounts. (b)–(f) Show the effect of training iterations and discretization granularity on the final CDF. The arrow in (c) highlights a common trend where the CDF converges to Nash from above as a finer discretization is introduced: coarser discretizations lead to under bidding and, in turn, underestimates of the auctioneer utility. (d) Shows that increasing training iterations reduces error, but in a less structured manner than bid granularity.
