    • The "world record" seems to be L= 1800 in Ref. 38, while Ref. 14, which studied a large number of samples using readily available algorithms from the LEDA package, went up to size L = 480.

    • note
    • We should point out that there are polynomial algorithms for the d=2 Ising model with periodic boundary conditions. For example Saul and Kardar (Refs. 48, 49) (see also Ref. 50) were able to compute the partition function at finite- T in polynomial time, but this method is not as efficient as the matching algorithm and so can only do rather small sizes, and, furthermore, it does not yield the ground state spin configuration. The more efficient transfer matrix approach of Merz and Chalker (Ref. 51), based on work by Cho and Fisher (Ref. 52), also unfortunately does not give the ground state spin configuration.

    • note
    • The original definition of a sponge-like excitation (Ref. 43) required the excitation to "wrap around" in all dimensions, which is only possible for d≥3. In two dimensions, we feel it is convenient to use the same term for excitations comprising two domain walls which wrap around in one direction.
