What the model is doing
A random monomer is displaced, then the move is accepted when it lowers energy—or sometimes when temperature supplies enough thermal freedom. FENE bonds limit stretching, Lennard–Jones interactions promote compact structures, and bending stiffness favors a straighter backbone.
