Born: November 10, 1942, Cesvaine, Latvia

  • Inductive Inference (Computational Learning Theory)
  • Randomized Algorithms (Complexity of Computation)
  • Mathematical Foundations of Computer Science

Brief Description of Main Research:

The primary area of Rusins Freivalds' research has always been complexity of computation. In 1975 he proved the very first theorem on advantages of randomized algorithms over deterministic ones. Namely, he has proven that randomized Turing machines can use less running time than deterministic ones to compute certain functions. Recently he has developed new powerful methods to prove lower bounds for time and space complexity of randomized algorithms.

Rusins Freivalds has published various results in Inductive Inference. He has tried to use deep methods of classical mathematics for problems in Theoretical Computer Science. Further areas of research: the usage of constructive ordinals to measure the complexity of Inductive Inference, and the usage of Group Theory in Inductive Inference.
