Sorry for spamming the postgresql group -- but this is database related, so let the elephants lead the charge!
Attached Files:
nested-set-1 => is a represenation of traditional nested set (operating on DAG) vs. chx implementation
chx2 => mfredrickson's visualization of what chx was describing.
chx2_updated => now with labels
chx_edge_case => a more degenerate DAG. Can chx's algorithm find the right numbers?
