In particular, after adding a subunit to a polymer such that the current length is $L'$, the following two steps are performed for every polymer $k$:

1.*Pruning*: If the weight $w_k^{(L')} < W_-^{(L')}$$, one of the following two actions is performed. Which of the two is performed is chosen randomly with equal probability (i.e. (a) with probability $1/2$ and (b) with probability $1/2$)

a. the polymer $k$ is discarded.

That means the current polymer length $L'$ is discarded and not used to grow further. However, the previous lengths of the polymer $k$ are still used for the averages for length $<L'$.

b. The weight $w_k^{(L')}$ is doubled: $w_k^{(L'), \text{new}} = 2 w_k^{(L')}$.
