Lance Jeremy Fortnow (born August 15, 1963) is a

interactive proof systems. As of January 2024, he was the Dean of the College of Computing at the Illinois Institute of Technology
.

Biography

Lance Fortnow received a doctorate in applied mathematics from

Fortnow was the founding editor-in-chief of the journal ACM Transactions on Computation Theory in 2009.

Work

In his many publications, Fortnow has contributed important results to the field of

NP-complete languages unless the polynomial hierarchy collapses.[9] With Michael Sipser, he also demonstrated that relative to a specific oracle there exists a language in co-NP that does not have an interactive protocol.[10]

In November 1989, Fortnow received an email from

NEXP.[13] These algebraic techniques were expanded further by Fortnow, Babai, Leonid Levin and Mario Szegedy when they presented a new generic mechanism for checking computations.[14]

Fortnow has continued to publish on a variety of topics in the field of computational complexity including

.

Fortnow's work in economics includes work in game theory, optimal strategies and prediction. With Duke Whang, he has examined the classic game theory problem of the

#P-hard and proposed an approximation technique for pricing permutation markets.[16] He has also contributed to a study of the behavior of informed traders working with LMSR market makers.[17]

Fortnow has also written a popular science book, The Golden Ticket: P, NP and the Search for the Impossible,[18] which was loosely based on an article he had written for CACM in 2009.[19] In his book, Fortnow provides a non-technical introduction to the P versus NP problem and its algorithmic limitations. He further describes his book and illustrates why NP problems are so important on the Data Skeptic podcast.[20]
