  We demonstrate that a temperature schedule for single-spin flip transition
matrix calculations can be simply and rapidly generated by monitoring the
average size of the Wolff clusters at a set of discrete temperatures.
Optimizing this schedule yields a potentially interesting quantity related to
the fractal structure of Ising clusters. We also introduce a technique in which
the transition matrix is constructed at a sequence of discrete temperatures at
which Wolff cluster reversals are alternated with certain series of single-spin
flip steps. The single spin-flip transitions are then employed to construct a
single transition matrix.
