Results of  on the benchmark sets B1, B2, and B3 (Figure adopted from ). Our method (see Figure 10) compares favorably with that of . Both the method of  and our method considered only periodicity as the sole criterion. We see that for the alpha factor experiment, our results are better for B3, comparable for B2, and inferior for B1. For the cdc15 experiment, our results are better for B1, B2, and B3. For the cdc28 experiment, our results are better for B1, while comparable for B2 and B3.
