David L. Applegate is an American computer scientist known for his research on the traveling salesperson problem.


Applegate graduated from the University of Dayton in 1984,[1] and completed his doctorate in 1991 from Carnegie Mellon University, with a dissertation on convex volume approximation supervised by Ravindran Kannan.[2]


Applegate worked on the faculty at Rice University and at AT&T Labs before joining Google in New York City in 2016.[1] His work on the Concorde TSP Solver, described in a 1998 paper, won the Beale–Orchard-Hays Prize of the Mathematical Optimization Society,[3][1][ICM] and his book The traveling salesman problem with the same authors won the Frederick W. Lanchester Prize in 2007.[4][TSP] He and Edith Cohen won the IEEE Communications Society's William R. Bennett Prize for a 2006 research paper on robust network routing.[5][ToN] Another of his papers, on arithmetic without carrying, won the 2013 George Pólya Award.[6][CMJ] In 2013, he was named an AT&T Fellow.[1]

With Guy Jacobsen and Daniel Sleator, Applegate was the first to computerize the analysis of the pencil-and-paper game, Sprouts.[7][8]
