Circuit rank
The cyclomatic number is a concept from the mathematical branch of graph theory.
Definition
Be a graph. The number of basic elements of a basic cycle, which is the dimension of the space is the cyclomatic number cycles.
Properties
- The index is never negative and vanishes if and only if it is in the graph is a forest.
- The index is never greater than the number of cycles of the graph and is then exactly equal to this number, if it is a cactus graph.
- The cyclomatic number can be represented by the formula
