Multiple time stepping can be applied to the leapfrog/Strrmer/Verlet integrator so as to effect a variable step size algorithm. The strategy maintains the symplecticness, time-reversibility, and second-order accuracy of the leapfrog method. This method can be applied to 2-body central force interactions by partitioning them into distance classes and smoothly decomposing the potential energy int...

Financial problems are one of the reasons why small and medium-sized industries (SMIs) in West Kutai have not developed optimally. Government assistance programs solutions. This program must be appropriate, so a decision-making tool is needed to help choose right SMIs assisted later. The weight criteria was determined using Analytical Hierarchy Process (AHP) technique, priority as preferred pro...
