Join-and-cut algorithm

An unusual two-SAW ensemble is employed in the join-and-cut algorithm, as will be discussed in Section 2.6.6.2. 

The dynamic critical behavior of the pivot + join-and-cut algorithm was studied in Ref. 165 by both analytical and numerical methods. For the relevant observable 2T= log[A i(JV(o( — A i)], the autocorrelation time in units of elementary moves is found to grow as Ti , x in d = 2. On... 

To obtain the critical exponent 7, use the join-and-cut algorithm (together with the pivot algorithm for the 7V-conserving moves).
