{"problem_background_main":"","problem_description_main":"Compute positions and velocities of a system of interaction particles that interact only via Newtonian gravity. Starting from a set of given initial positions and velocities compute future values using the classical fourth order accurate Runge-Kutta method. The state vector is a N by 6 (where N is the number of particles) float array \"u\" of positions and veclocities which is updated at at step.","problem_io":"'''\nInput\nuin: a 2D array of initial positions and velocities. N,6 elements; each element is a float; each particle is described by its location and velocity, first the $x$,$y$,$z$ position of the particle followed by the $vx$,$vy$,$vz$ velocity of the partile. Thus particle \"i\"'s position and velocity are stored in uin[i][0],uin[i][1],uin[i][2],uin[i][3],uin[i][4],uin[i][5].\nmass: an 1D array of particle masses; an array of floats\nt1: final time that positions and velocities are evolved to; a float\ndt: time step to use for the evolution; a float\n\nOutput\nuout: a 2D array of final positions and velocities, N,6 elements; each element is a float; laid out like uin\n'''","problem_name":"nbody","required_dependencies":"import numpy as np"}
