31. The original multiple-spin method applies only to coupling constants with values of ±1. Nevertheless, it can be extended to our case, floating point constants. To do this, we need more than one set of coupling constants. We calculate the energy for each set and then sum them with different weights. In this work, we use 20 replicas to get smooth values between -1 and +1 for J.
32. One should be aware of the fact that the results span only an order of magnitude.
