The computer system of claim 8 , wherein the instructions when executed by the processor further include: determining a second order sequential statement having a largest number of appearances based on a third PTCT, wherein a third EPTT catalogs each statement having a respective step number sequential to and greater than a respective step number of the first order sequential statement, wherein the third PTCT records a respective number of appearances of each statement based on the third EPTT; and storing each appearance of the statement having a largest number of appearances, the first order sequential statement having a largest number of appearances, and the second order sequential statement having a largest number of appearances in the KRLT as the largest common series.
14. The computer system of claim 13 , wherein determining a sequential statement having a largest number of appearances from a previous sequential statement and storing each appearance of the sequential statement in the KRLT is repeated for sequential statements that appear more than once in the one or more sets of ordered statements.
