class TrialReptate : public feasst::TrialMove

Reptate a linear chain by taking one end and adding it to the other end. For heteropolymers, this perturbation changes the composition of all particles with the same type. Thus, individual heteropolymers should be added as unique particle types. The bond length is taken as the bond between site 0 and 1, and is assumed to be constant. Thus, as currently implemented, heteropolymers must have the same bond length. This trial may not be compatible with angle and dihedral potentials. Instead, use “reptate” in TrialGrow.
