- PyDAG.merge_nodes(u, v, /)#
Merge two nodes in the graph.
If the nodes have equal weight objects then all the edges into and out of u will be added to v and u will be removed from the graph. If the nodes don’t have equal weight objects then no changes will be made and no error raised
u (int) – The source node that is going to be merged
v (int) – The target node that is going to be the new node
