nodecomp()

def nodecomp	(		self,
			node1,
			node2
	)

compare two leaves of the current branching tree

It should return the following values:

  value < 0, if node 1 comes before (is better than) node 2
  value = 0, if both nodes are equally good
  value > 0, if node 1 comes after (is worse than) node 2.

(

self

)

executed before the transformed problem is freed

(

self

)

executed before the branch-and-bound process is freed

(

self

)

frees memory of node selector

Definition at line 6 of file nodesel.pxi.

nodeinit()

def nodeinit

(
