Eotvos Lorand University professor Laszlo Lovasz, who has solved several information technology (IT) problems using graph theory, has been awarded the Kyoto Prize. "Graph theory represents a different approach to optimization problems that uses geometry to compute results instead of differential equations," says Lovasz. "It turns out that very large networks in many different fields can be described by graphs, from cryptography to physical systems."
Lovasz's work has led to breakthroughs in RSA encryption technology, 4G channel capacity, extending the point-to-point IT of Claude Shannon, and the weak perfect graph conjecture. Lovasz may be best known for the breakthrough principles called the "Lovasz local lemma" and the "LLL-algorithm," which are widely used in cryptography, and for the multiple-input and multiple-output wireless communications scheme.
The Kyoto Prize was founded by Kyocera chairman Kazuo Inamori in 1984 and comes with a $550,000 award.
