There is a strictly 2-competitive de-terministic online algorithm. In fact, a competitive ratio of 2 is achieved by the most na ve algorithm: the greedy algorithm that matches each new vertex j to an arbitrary unmatched neighbor, i, whenever an unmatched neighbor exists.

"WebAug 6, 2024 · In my other post, I describe my algorithm as follows: My idea to solve this was that you should start with the person who has the fewest compatibilities, and match them with the person that they're connected to that has the fewest compatibilities. For example, since Joe is only connected with Jill, you should match them first. " - Greedy match algorithm

Greedy match algorithm

WebThe greedy method, an iterative strategy that seeks for an optimum solution by constantly selecting the best choice in the current state, is how the greedy algorithm operates. The Greedy Algorithm also employs a graph-search strategy, an iterative method that looks for the best answer by taking the edges and nodes of the graph into account. 6.
