WebThe graph realization problem is that of computing the relative locations of a set of vertices placed in Euclidean space, relying only upon some set of inter-vertex distance measurements. This paper is concerned with the closely related problem of determining whether or not a graph has a unique realization. Both these problems are NP-hard, but … WebThe problem uniform sampling a directed graph to a fixed degree sequence is to construct a solution for the digraph realization problem with the additional constraint that such each solution comes with the same probability. This problem was shown to be in FPTAS for regular sequences by Catherine Greenhill The general problem is still unsolved. 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. hills bridge rail and construction ltd
