Abstract
A subgraph isomorphism algorithm using 2D continuous Hopfield neural network is presented in this paper. Given two graphs G 1 and G 2, the goal is to find a subgraph of G 2 isomorphic to G 1. The rows of the 2D neuron array represent the vertices of G 1, and the columns represent those of G 2. The energy function is defined. The network parameters are deduced from the energy function. The neurons are initialized based on the necessary conditions for subgraph isomorphism. The motion equation is solved using the fourth order Runge-Kutta method. Experimental results show the correctness and validity of the algorithm.
