The study of the classical three-body problem lasts nearly 300 years. But some concrete examples have been obtained only by computers in the general three-body problem. For the first time, such works were begun at the Astronomical Observatory of Leningrad State University in 1965 by T.A. Agekian and J.P. Anosova, Later V.V. Orlov has joined them. During 20 years the extensive studies have been carried on — more than 30 000 runs have been considered by the computer simulations.
