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. WebJan 8, 2024 · We study the graph realization problem in the Congested Clique in a distributed network under the crash-fault model. We focus on the degree-sequence realization, 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 given …

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 ... Webbipartite graph can be naturally formulated as a graph-partitioning problem, which aims at getting the vertex partition with minimum cut (Dhillon 2001; and Zha et al. 2001).
