Multistage Graph 
DEFINITION
A Multistage graph is a directed, weighted graph in which the nodes can be divided into a set of stages such that all edges are from a stage to next stage only
Key Concepts
Stages: Vertices are divided into several stages (Stage 1, Stage 2, ...,).
-
-
Edges: Directed edges exist only from one stage to the next (not within the same stage or going backwards).

Algorithm Steps
-
-
-
For each node, calculate:
-
-
-
-
-
Limitations
Only works on acyclic, layered graphs
Can’t model complex non-layered systems without modifications
Example
-
-
-
D → G = 2, E → G = 1, F → G = 3
