Albert Tucker was an influential Australian mathematician known for his work in game theory and optimization. He is best recognized for the Tucker decomposition, a mathematical concept that generalizes the singular value decomposition to higher dimensions. His contributions have had a lasting impact on various fields, including economics, engineering, and computer science. Born in 1914, Tucker earned his Ph.D. from Princeton University and later became a professor at Stanford University. Throughout his career, he collaborated with notable mathematicians and contributed to the development of the Prisoner's Dilemma, a fundamental problem in game theory that illustrates the complexities of cooperation and competition.
