36 Perturbation Theories for Fluids and Solids
this problem (Siepmann 1990, Frenkel et al. 1992, de Pablo et al. 1992, 1993,
Siepmann and Frenkel 1992). These procedures are ultimately based on a much
earlier method (Rosenbluth and Rosenbluth 1955) developedto sample configurations
of molecular chains from MC simulation considering the problem as a self-avoiding
walk on a lattice. To this end, a chain consisting of M equal segments was constructed
on a cubic lattice by placing the start of the first segment at a random position in
the lattice, then one of the six neighboring positions is chosen at random to place
the other end of the segment and the start of a new segment, next a new neighboring
position is selected randomly, with the restriction
