Greedy algorithm interval scheduling
WebOct 30, 2016 · I have found many proofs online about proving that a greedy algorithm is optimal, specifically within the context of the interval scheduling problem. On the second page of Cornell's Greedy Stays Ahead handout, I don't understand a few things: All of the proofs make the base case seem so trivial (when r=1). WebInterval Scheduling: Greedy Algorithms Greedy template. Consider jobs in some natural order. Take each job provided it's compatible with the ones already taken. [Earliest start time] Consider jobs in ascending order of s j. [Earliest finish time] Consider jobs in ascending order of f j. [Shortest interval] Consider jobs in ascending order of f j-s
