Detailed Description

Represent the ILP of the subDAG rooted at a DAG node.

ILPValues summarize the DAG subtree rooted at each node. ILPValues are valid for all nodes regardless of their subtree membership.

When computed using bottom-up DFS, this metric assumes that the DAG is a forest of trees with roots at the bottom of the schedule branching upward.
