As far as I understand:
- Pruning means deleting something.
- Enrich means to enhance/increase weight.
Now my question is, in the case of pruned-enriched Rosenbluth method (PERM):
For pruning/enriching, are we deleting/adding to some polymers chains or are we deleting/adding some beads in all polymer chains?
Basically, when we are updating the weights, what are we replacing them with?
