desired and the actual correlation distributions is defined as the energy
function E of the system. The configuration of BCF can be viewed as the state
variable of the system. The remaining task is to optimize the state variable of
the system; that is, the configuration of the BCF, so that a global minimum
energy state can be achieved.

thesizing a BCF as shown in Fig. 2.34 is described in the following:
