WebNov 15, 2016 · Here's an O(n log n) algorithm: Instead of looping through all n intervals, loop through all 2n interval endpoints in increasing order. Maintain a heap (priority queue) of available colours ordered by colour, which initially contains n colours; every time we see an interval start point, extract the smallest colour from the heap and assign it to this interval; … WebGreedy Algorithm. Greedy algorithm is a simple and heuristic algorithm that follows the problem-solving heuristic of making the locally optimal choice which might but not necessarily end up a global optimal solution. It builds up a solution piece by piece, always choosing the next piece that offers the most obvious and immediate benefit.

WebA greedy algorithm constructs a solution to the problem by always making a choice that looks the best at the moment. A greedy algorithm never takes back its choices, but directly constructs the final solution. For this reason, greedy algorithms are usually very efficient.
