A PARTIAL FORCE BIAS MONTE CARLO SCHEME AND ITS APPLICATION IN CALCULATING RELATIVE FREE ENERGY
部分力偏倚蒙特卡罗方法和它在计算相对自由能中的应用

A partial force bias scheme is proposed for the Monte Carlo simulation in which the transtation of each molecule's mass center is biased in the direction of force on it , but no bias for rotations. The total efficiency is better than previous schemes. Its application to a calculation of free energy is reported.
