WebAug 6, 2015 · The heavy-light (H-L) decomposition of a rooted tree is a method of partitioning of the vertices of the tree into disjoint paths (all vertices have degree two, except the endpoints of a path, with degree one) that gives important asymptotic time bounds for certain problems involving trees. It appears to have been introduced in passing in Sleator … asu international relations // A more complete description is on e-maxx. (in Russian) Heavy-light decomposition — this is such a decomposition of graph into disjoint paths at the vectixes or edges that on the way from any node to the root of this tree we will change no more than log(N)paths. If we can build such paths then with the help of additional … See more The first time I tried to write this structure to the problem, the code was, to put it mildly, a rather big.
