If
W and
W_new are the same, why then treat them separately below?

split.min_sum += (*split.Y)[individual][p] * log(W[individual][p] / (1 + std::accumulate(W[individual].begin(), W[individual].end(), 0.0)) ); // ~ R_old |

split.min_sum -= (*split.Y)[individual][p] * log(W_new[individual][p] / (1 + std::accumulate(W_new[individual].begin(), W_new[individual].end(), 0.0)) ); // ~ R_new |
W and
W_new are the same, so nothing happens?
And won't this give
log(0) in some cases?
