Rosenbluth factor

Once the entire chain is grown, the normalized Rosenbluth factor for this configuration is calculated... 

The normalized Rosenbluth factor of the isolated chain has to determined from a separate (but very fast) simulation. A related technique, the orientational-bias insertion [2,39,40] is suitable for fluids where part of the interactions is strongly orientation-dependent. 

Similarly, to construct the reverse move, a new set of A — 1 orientations is generated about the old positions, and the Rosenbluth factor of the original configuration of the molecule, R, is calculated. 

Step 2 is repeated until the entire chain is grown and we can determine the Rosenbluth factor of configuration n ... 

Once the entire chain has been retraced, we determine its Rosenbluth factor ... 

The Rosenbluth factors of the other t — 1 segments are calculated as follows. We consider the calculation of the... 

Rosenbluth factor of segment /. We generate a set of k — 1 orientations with a distribution prescribed by the bonded interactions (14). These orientations, together with the actual bond between segment — I and /. form the set of k orientations bo. b ). These orientations are used to calculate the external Rosenbluth factor. 

For the entire chain the Rosenbluth factor of the old conformation is defined by... 

Among Q processors, g new (u) chains of length N are distributed and grown using the standard CBMC algorithm. To avoid load imbalance, mod (g, Q) = 0 must hold. For the selection of trial segments, u is used only. This results in a Rosenbluth factor W for each chain...
