Graph isomorphism (sopuli.xyz)

Definitions

A graph G = (V, E) is a set of nodes V and a set of undirected edges E. An undirected edge is a set of two vertices.

Two graphs G1 = (V1, E1) and G2 = (V2, E2) are isomorph if there is a bijective mapping f from V1 to V2 such that f(E1) = E2. Applying f to E1 means applying it to each node in each edge in E1.

Problem

Is there an algorithm that decides if two arbitrary graphs are isomorphic in polynomial time?

That's why I'm asking
