Web3 Example problems When it’s phrased in terms of graphs, Hall’s looks quite abstract, but it’s actually quite simple. We just have to remember the keys to using Hall’s: matching things comes up in lots of di erent ways, and, the matching condition is the only one we need. Let’s go back to our previous problem. Problem 1. WebJul 7, 2024 · What if the degrees of the vertices in the two graphs are the same (so both graphs have vertices with degrees 1, 2, 2, 3, and 4, for example)? Draw two such …
