Graph Isomorphism … WebJul 7, 2024 · Let f: G 1 → G 2 be a function that takes the vertices of Graph 1 to vertices of Graph 2. The function is given by the following table: Does f define an isomorphism between Graph 1 and Graph 2? Explain. Define a new function g (with g ≠ f) that defines an isomorphism between Graph 1 and Graph 2.

WebGraph isomorphism is a hard problem (conjectured to be somewhere between P and NP-complete). Entire books have been written about it. It is unreasonable for you to expect a description of a graph-isomorphism algorithm on Stack Overflow (although some version of brute-force for smallish graphs is reasonable enough).
