The graph realization problem is a decision problem in graph theory. Given a finite sequence $${\displaystyle (d_{1},\dots ,d_{n})}$$ of natural numbers, the problem asks whether there is a labeled simple graph such that $${\displaystyle (d_{1},\dots ,d_{n})}$$ is the degree sequence of this graph. See more The problem can be solved in polynomial time. One method of showing this uses the Havel–Hakimi algorithm constructing a special solution with the use of a recursive algorithm. Alternatively, following the characterization … See more The problem can also be stated in terms of symmetric matrices of zeros and ones. The connection can be seen if one realizes that each graph has an See more Similar problems describe the degree sequences of simple bipartite graphs or the degree sequences of simple directed graphs. … See more WebWe study graph realization problems from a distributed perspective. The problem is naturally ap-plicable to the distributed construction of overlay networks that must satisfy certain degree or con-nectivity properties, and we study it in the node capacitated clique (NCC) model of distributed

WebFinding a graph with given degree sequence is known as graph realization problem. An integer sequence need not necessarily be a degree sequence. Indeed, in a degree … WebMay 4, 2024 · Background. Given a degree sequence d of length n, the degree realization problem is to decide if d has a realization, that is, an n-vertex graph whose degree sequence is d, and if so, to construct such a realization (see [1, 10, 12,13,14, 16,17,18,19]).The problem was well researched over the recent decades and plays an … WebGiven a (0,1 }-matrix M, the graph-realization problem is to determine a connected graph G, if one exists, such that M is a fundamental matrix for G. M is then said to be graphic and G is a realization of M. This definition is equivalent to the one in the Introduction.
