New method encodes hypergraphs into strings for isomorphism testing

Researchers have developed IsalHG, a novel method for encoding finite, connected hypergraphs into strings using a compact instruction alphabet. This method employs a virtual machine with a sparse hypergraph, a circular doubly-linked list, and traversal pointers to represent hypergraph structures. A greedy algorithm generates a string representation, and a conjectured canonical string is proposed as a complete isomorphism invariant, potentially enabling native hypergraph isomorphism testing.
