A numerical code was constructed for the study of the evolution of interacting binary galaxies. This "multiple three-body" algorithm (MTBA) essentially involves N concurrent three-body integrations. MTBA incorporates a violent relaxation phase that allows the particles to redistribute themselves in the gravitational field of the perturber prior to the full binary orbital evolution calculation. This redistribution is important for systems with an initially strong tidal potential; their predicted merger times are 50-100% larger than previously estimated. Merger times are tabulated both for circular and for elliptical orbits. Typical close binary galaxies will merge in about twice their initial binary oribtal periods. A specific interacting binary simulation is described in detail in the first paper. Many of the results reported here are consistent with those obtained from the larger, more expensive N-body simulations. MTBA is altered so that each "galaxy" is represented by a configuration of test particles.
