We show how to adapt an existing non-DFS-based accepting cycle detection algorithm OWCTY [10,15,29] to the I/O efficient setting and compare its I/O efficiency and practical performance to the existing I/O efficient LTL model checking approach of Edelkamp and Jabbar [14]. The new algorithm exhibits similar I/O complexity with respect to the size of the graph while it avoids quadratic increase in the size of the graph. Therefore, the number of I/O operations performed is significantly lower and the algorithm exhibits better practical performance.
