Comment on Breaking the Sorting Barrier for Directed Single-Source Shortest PathsComments−gsliepen1yAt first glance it looks like this is very useful, but it only gives a speedup for very sparse graphs with an average degree of less than 3, unless your graph is very big, as in trillions of vertices.−MarkusQ1yDegree less than 6? If m < 3n that means there are three times as many edges as nodes, and each edge connect to two vertices.So 2d square latices would still benefit.But yeah, not a total domination.
