69 | * replaces them accordingly. Then it searches for sub sequences being the |
---|
70 | * longest and occurring most often. For each found sub sequence, it replaces |
---|
71 | * the occurrences by creating appropriate {@link ISequence}s. Afterwards, again |
---|
72 | * searches for iterations and then again for sub sequences until no more |

73 | * replacements are done. |
