"Grove City Math Prof, Business Colleagues Receive Patent"
"GROVE CITY, Pa. - Grove City College mathematics professor Ralph Carlson is part of a three-person team to be awarded a patent from the U.S. Patent Office on June 15. The patent seeks to solve the problem of searching through hundreds of thousands or millions of electronic documents for a particular word or character string.Carlson and his colleagues, Thomas Kraay and Charles Brisbin, was issued the patent for his work on an algorithm capable of solving the problem of rapidly identifying which documents contain a particular character string from a multitude of documents. Kraay and Brisbin are consultants for a private company, Ultimate Solutions LLC, for which Carlson is a partner.The algorithm is a somewhat unusual approach to this classic problem and uses a combination of bit strings, pseudorandom number generators and probability theory in its solution, Carlson explains. The algorithm plays a critical role in the development of a suite of software tools designed to aid law enforcement and national security agencies in their assigned missions.Carlson, a member of the faculty since 2000, is a 1962 graduate of Grove City College. He received his master's and Ph.D. from the University of Pittsburgh. Grove City College, founded in 1876, is a private Christian college teaching the liberal arts, sciences and engineering. It is an advocate of the free market economic system and accepts no federal funding. Visit Grove City College: www.gcc.edu"
