Greedy exchange
WebExchange Argument Let 𝐴=𝑎1,𝑎2,…,𝑎𝑘 be the set of intervals selected by the greedy algorithm, ordered by endtime OPT= 1, 2,…, ℓ be the maximum set of intervals, ordered by endtime. Our goal will be to “exchange” to show 𝐴has at least as many elements as OPT. Let 𝑎𝑖, 𝑖 be the first two elements where 𝑎𝑖 WebExchange Arguments Exchange arguments are a powerful and versatile technique for proving optimality of greedy algorithms. They work by showing that you can iteratively …
