- Convert the tree structure to a flow.
- compute the potential and the reduced costs.
- Select an arc to pivot, keeping the strong feasibility of the tree when changing the arcs on the tree!
Strong feasibility of the tree is at pg 421
-
We now state two alternate definitions ofa strongly feasible spanning tree.
strong feasible spanning tree solution definition.
-
Theorem 11.9 (Triangularity Property).
the incidence matrix of a spanning tree graph can be, lower triangular.
-
the basic idea in the procedure is tostart at node 1 and fan out along the tree arcs using the thread indices to computeother node potentials.
The starting node is, the first element from
thread. First node from the in-order tree traversal. -
