A Middlesex County College student club, called Middlesex, Math & the Mouse, heard from a best-selling author in November about how to apply mathematics and data to saving time. The lecture, by Len Testa, was titled “The Traveling Salesman Problem for Fun and Profit.” Mr. Testa is a best-selling author, computer scientist, and data guru. He holds a U.S. patent on the programing methods used to solve the problem of how to save up to four hours waiting on lines at Walt Disney World. He is also the president of Touring Plans and leads the researchers for all of The Unofficial Guides travel book series. He explained how he applied academic research on the time-dependent traveling salesman problem to figure out how to avoid the lines at Walt Disney World, Disneyland, Universal Studios Orlando. Before his speech, he talked with club members, from left, Shayne Judge (Piscataway), club president; Lauren Sutphen (Port Reading), secretary; Alyssa Capone (South Plainfield), treasurer; and mathematics professor Patty Kiernan (Piscataway), club advisor.
