WebJul 21, 2024 · The research conducted under this grant contributed to developments in three areas: (i) discrete and convex geometry via the study of realization spaces of polytopes, (ii) extremal graph theory via sums of squares certificates for graph density inequalities and (iii) computer vision via algebraic and semialgebraic approaches to geometric problems in … WebDigraph realization problem. The digraph realization problem is a decision problem in graph theory. Given pairs of nonnegative integers , the problem asks whether there is a … 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 how to set up imessage on iphone 13 pro max
