Yes, the Knuth-Morris-Pratt (KMP) algorithm involves a preprocessing step to compute the partial match table, which is an array that stores the lengths of the longest proper suffixes of each prefix of the pattern.

The KMP algorithm is sometimes referred to as the Knuth-Morris-Pratt-Powell algorithm, as it was independently discovered by James H. Morris and Vaughan Pratt, and later simplified and published by Donald Knuth. The algorithm is also sometimes called the "MP" algorithm, after Morris and Pratt.
