A logic circuit is presented that detects cycles in an n-node state graph in o(n) basic operations. This compares favorably with software for cycle detection that requires 0(n<sup>2.8</sup>) operations and is, therefore, useful in situations where real-time detection is important.
Complexity, cycle detection, hardware, state diagram.
