Greedy nearest neighbor algorithm

WebAug 29, 2024 · I know that solving a TSP requires considering all possible cycles in the graph, and that a nearest neighbor greedy algorithm does not always produce the shortest path. I found this answer that gives a counterexample for such a greedy algorithm, but it only consider starting from a specific vertex (A).

WebThe default nearest neighbor matching method in M ATCH I T is ``greedy'' matching, where the closest control match for each treated unit is chosen one at a time, without trying to minimize a global distance measure. In contrast, ``optimal'' matching finds the matched samples with the smallest average absolute distance across all the matched pairs. WebWe refer to these four algorithms as greedy nearest neighbor matching (high to low), greedy nearest neighbor matching (low to high), greedy nearest neighbor matching (closest distance), and greedy nearest neighbor matching (random), respectively.
