Authors: A. Giorgilli | ||

Program title: COSTANTI DEL MOTO | ||

Catalogue identifier: ACYO_v1_0Distribution format: gz | ||

Journal reference: Comput. Phys. Commun. 16(1979)331 | ||

Programming language: Fortran. | ||

Computer: UNIVAC 1106. | ||

Operating system: UNIVAC 1106 EXEC 8. | ||

RAM: 42K words | ||

Word size: 36 | ||

Keywords: Astrophysics, Celestial mechanics, Classical mechanics, Stellar systems, Integrals of motion, Stars. | ||

Classification: 1.7. | ||

Nature of problem:The classical problem of constructing formal integrals for a Hamiltonian of harmonic oscillators coupled by polynomial interactions is considered. | ||

Solution method:An algorithm recently proposed is applied which allows very fast computation of the integrals. | ||

Restrictions:The restrictions, imposed by array dimensions, are described in tdetail in the long write up. | ||

Running time:The computation of one integral up to order 8 for a model with 2 degrees of freedom required an execution time of about 25 s on the UNIVAC 1106. |
