Consider the generalization of the renter’s dilemma where Alice can buy or rent her skis separate from her boots. Say that renting skis costs a dollars, whereas buying skis costs b dollars. Likewise, say that renting boots costs c dollars, whereas buying boots costs b dollars. Describe a 2-competitive online algorithm for Alice to try to minimize the costs for going skiing subject to the uncertainty of her not knowing how many times she will continue to go skiing in the future.
