Webbe the hotel you stop at on night 𝑖in the greedy algorithm. Let 𝑇𝑖 be the hotel you stop at in the optimal plan (the fewest nights plan). Claim: 𝑔𝑖 is always at least as far along as 𝑇𝑖. Base Case: 𝑖=1, OPT and the algorithm choose between the same set of hotels (all at most 500 miles from the start), 𝑔𝑖 Web–Let k be the number of rooms the greedy algorithm uses and let R be any valid schedule of rooms. There exists a t such that at all time, k events are happening simultaneously. So R uses at least k rooms. So, R uses at least as many rooms as the greedy solution. Therefore, the greedy solution is optimal. CSE 101, Fall 2024 18
