Detailed Description

Configuration bias reptation move for a Linear species.

A reptate move uses a configuration bias algorithm to add a segment to one end of a chain (the head) and delete one from the other (the tail). The direction of the move (i.e., which end is the head) is chosen at random. The only parameter is nTrial, the number of trial positions for the new position of the head monomer.
