Synopsis

This mcMove implements the configuration bias algorithm for regrowing segments at either end of a flexible linear polymer. It generates trial positions with bond lengths chosen from a Boltzmann distribution, with random bond orientations. Angle and external potentials are included in the Rosenbluth weight, but not in the generation probabilities.

This algorithm is designed for use with flexible linear chains with stiff bond potentials, and chains with soft angle potentials. It is correct but inefficient for models with stiff angle potentials.
