James Kennedy (social psychologist)

James Kennedy (b. November 5, 1950 - ) is an American social psychologist, best known as an originator and researcher of particle swarm optimization. The first papers on the topic, by Kennedy and Russell C. Eberhart, were presented in 1995; since then more than a thousand papers have been published on particle swarms. The Academic Press / Morgan Kaufmann book, Swarm Intelligence, by Kennedy and Eberhart with Yuhui Shi, was published in 2001.

The particle swarm paradigm draws on social-psychological simulation research Kennedy had participated in at the University of North Carolina, integrated with evolutionary computation methods that Eberhart had been working with in the 1990s. The result was a problem-solving or optimization algorithm based on the principles of human social interaction. Individuals begin the program with random guesses at the problem solution. As the program runs, the "particles" share their successes with their topological neighbors; each particle is both teacher and learner. Over time, the population converges reliably on optimal vectors.

Dr. Kennedy is an active combatant in the controversy over sex education in Montgomery County, Maryland, supporting the public schools' efforts to develop a comprehensive and inclusive program. He also worked as a professional musician for twenty years.

Based on the back cover of his 2001 "Swarm Intelligence" book, Dr Kennedy works in survey methods at the US Department of Labor, has conducted basic and applied research into the social effects on cognition and attitude. He has worked with particle swarms since 1994.
