Figure 1: In (a) are represented several profit functions,
with representing
the profit function in round . In (b) is represented the warranty offered,
as a function of the round number, by various algorithms. (c) represents
the profit earned, as a function of the round number, by each algorithm.
Finally, (d) represents the average regret of the two algorithms, and . The algorithm “opt_fixed” selects a single,
optimal warranty for all rounds. The algorithm “opt_round” selects the
optimal warranty in each round.
