WebI liked the problem, I didn't like the TL constraints. I mean, it's an algorithmic contest, so when you write O(N) solution instead of the "intended" O(N*logN) you are supposed to pass. But no — since you are using the standard library of a specific implementation of specific language you fail, even though your solution is correct (and will pass, if the system used … WebAug 26, 2014 · Part 1: If M is a matroid, then greedy works perfectly no matter the cost function. Part 2: If greedy works perfectly for every cost function, then M is a matroid. Proof of Part 1. Call the cost function w: X → R ≥ 0, and suppose that the greedy algorithm picks elements B = { x 1, x 2, …, x r } (in that order).

This algorithm ignores the fact that the current best result may not bring about the overall optimal result. Even if the initial decision was incorrect, the algorithm never reverses it.

WebGreedy algorithms tend to be made up of five components. These components include: A candidate set from which a solution is created. A selection function, which picks the best candidate that will be added to the solution. A feasibility function. This is used to determine whether a candidate can be used to contribute to a solution.
