WebInterval Scheduling: Greedy Algorithm Greedy algorithm. Consider jobs in increasing order of finish time. Take each job provided it's compatible with the ones already taken. Running time: Θ( log ). Remember the finish time of the last job added to … WebSep 17, 2024 · Maximum interval scheduling - Circular Variation. Consider a variant of interval scheduling except now the intervals are arcs on a circle. The goal is to find the maximum number of arcs that do not overlap. Let C be the circle on the plane centered at the origin with unit radius. Let A 1,..., A n be a collection of arcs on the circle where an ...
