We describe a hybrid algorithm to calculate the formation of planets from aninitial ensemble of planetesimals. The algorithm uses a coagulation code totreat the growth of planetesimals into oligarchs and explicit N-bodycalculations to follow the evolution of oligarchs into planets. To validate theN-body portion of the algorithm, we use a battery of tests in planetarydynamics. Several complete calculations of terrestrial planet formation withthe hybrid code yield good agreement with previously published calculations.These results demonstrate that the hybrid code provides an accurate treatmentof the evolution of planetesimals into planets.Comment: Astronomical Journal, accepted; 33 pages + 11 figure
