-    "For the **decision** step, we need to make a subroutine that either accepts or rejects the new conformatuon based on the Metropolis criterion. The Metropolis criterion has a probability of accepting a move as $P = \\exp( -\\Delta G / kT )$. When $ΔE ≥ 0$, the Metropolis criterion probability of accepting the move is $P = \\exp( -\\Delta G / kT )$. When $ΔE < 0$, the Metropolis criterion probability of accepting the move is $P = 1$. Use $kT = 1$ Rosetta Energy Unit (REU)."
