Research Type Experimental We also report the results of empirical evaluations comparing our algorithm with the previous state of the art and show a consistent exponential improvement in several different scenarios. 6 Empirical results In this section, we present the result of simulations comparing the monotone algorithm and our algorithm PFSr.

Experiment Setup Yes The experiments were carried out as follows: given a buyer s valuation v, a discrete set of false valuations bv were selected out of the set {.03, .06, . . . , v}. Both algorithms were run against a buyer making the seller believe her valuation is bv instead of v. The value of bv achieving the best utility for the buyer was chosen and the regret for both algorithms is reported in Figure 2. We considered two sets of experiments. First, the value of parameter γ was left unknown to both algorithms and the value of r was set to log(T). ... For the second set of experiments, we allowed access to the parameter γ to both algorithms. The value of r was chosen optimally based on the results of Theorem 1 and the parameter β of monotone was set to 1 1/ p TTγ to ensure regret in O( p T).
