Graph realization problem
WebThe degree sequence problem asks essentially this, does there exist a graph that achieves the specified degrees of nodes? Also called the graph realization problem. The Havel … WebMar 16, 2024 · The vertex-weighted realization problem is now as follows: Given a requirement vector f, find a suitable graph G and a weight vector w that satisfy f on G (if exist). In the original degree realization problem, the requirements are integers in [0,n-1] and all vertex weights must equal one.

WebIt turns out that any graph at all can be realized in 3-space because there is enough "room" so that the edges can be chosen in a way so they meet only at the vertices. It is typically hard to determine the minimum number of holes so that the graph can be drawn on a torus with that number of holes. This is the problem of determining the genus ... http://maths.hfut.edu.cn/info/1039/6076.htm
WebDec 13, 2024 · In this paper, we study the graph realization problem in the Congested Clique model of distributed computing under crash faults. We consider degree-sequence realization, in which each node v is associated with a degree value d(v), and the resulting degree sequence is realizable if it is possible to construct an overlay network with the … WebApr 18, 2024 · 1.2.
