Digraph realization problem: Related problems, Solutions & Other notations
The digraph realization problem is a decision problem in graph theory. Given pairs of nonnegative integers ( ( a 1 , b 1 ) , … , ( a n , b n ) ) {\displaystyle ((a_{1},b_{1}),\ldots ,(a_{n},b_{n}))} , the problem asks whether there is a labeled simple directed graph such that each vertex v i {\displaystyle v_{i}} has indegree a i {\displaystyle a_{i}}…
