Competitive online algorithm. In this section, we show a randomized algorithm with competitive ratio 1 + 1 (1+1=B)B 1, which is roughly e e 1 because as Bgets large, (1 + 1=B)B ˇe, and the ratio goes down to e e 1. Note that the worst case is 2 when B= 1, but Bshould be more than 1 because otherwise we will not rent skis at all. ... Fetch Content
