Check for Isomorphism in Hypergraphs

Click For Summary
The discussion focuses on checking isomorphism between two hypergraphs using MATLAB, highlighting the inefficiency of a brute force permutation method. A suggestion was made to represent the hypergraphs as bipartite graphs to check for isomorphism, but concerns were raised about the potential for non-isomorphic hypergraphs to have isomorphic bipartite representations. The participants also considered applying Whitney's theorem for hypergraph isomorphism but lacked familiarity with its specifics. The ideal solution would be a readily available algorithm for hypergraph isomorphism. The thread seeks further insights or updates on the topic.

Hi,

I was trying to check whether two hypergraphs are isomorphic to each other using MATLAB. I did the brute force method by permuting the vertices and check all the permutations one by one. This method is pretty slow.

An idea suggested by my friend was to represent the hypergraphs as bipartite graphs and check whether the two bipartite graphs are isomorphic instead. However, we are unsure whether two non-isomorphic hypergraphs might have isomorphic bipartite graphs. Can someone enlighten us about this?

Furthermore, we thought of applying Whitney theorem to check for isomorphism, but we are not familiar with the theorem for hypergraph.

Of course it will be best if there is a readily available algorithm to check for isomorphism in hypergraphs. :)

Thanks for the post! Sorry you aren't generating responses at the moment. Do you have any further information, come to any new conclusions or is it possible to reword the post?
 
Here is a little puzzle from the book 100 Geometric Games by Pierre Berloquin. The side of a small square is one meter long and the side of a larger square one and a half meters long. One vertex of the large square is at the center of the small square. The side of the large square cuts two sides of the small square into one- third parts and two-thirds parts. What is the area where the squares overlap?
