Where P is number of predicate nodes in flow graph V(G).
Cyclomatic Complexity Using Predicate Nodes
Cyclomatic complexity, denoted as $V(G)$, is a software metric used to indicate the complexity of a program or flow graph. It directly relates to the number of linearly independent paths through the code.
A common formula for calculating cyclomatic complexity, particularly when focusing on decision points, uses the number of predicate nodes.
A predicate node is a node in a flow graph that corresponds to a conditional statement (like an if, while, or case statement) which controls the flow. The formula is:
$ V(G) = P + 1 $
Where $P$ represents the total number of predicate nodes within the flow graph $V(G)$.
This formula provides a straightforward way to quantify complexity based on the number of decision points.
Therefore, the correct representation of cyclomatic complexity in terms of predicate nodes (P) is $P + 1$.
