Initial-Value Problems

Methods for solving initial-value problems

• Scalar/systems of 1st-order ordinary differential equations (ODEs)
  • Runge-Kutta methods
    • Fixed-step or adaptive-step using step-doubling (orders 1 to 8)
    • Runge-Kutta-Fehlberg methods (orders 1 to 8)
  • Linear Multistep methods
    • Adams-Bashforth-Moulton Predictor-Corrector (orders 1 to 5, fixed-step)
• Direct methods for solving 2nd-order ODEs
  • Problems of the special form $\frac{d^{2}y}{d{t}^2}=f(t,y)$
    • Runge-Kutta-Nystrom methods (work in progress)
  • General second-order ODEs $\frac{d^{2}y}{d{t}^2}=f(t,y,\frac{dy}{dt})$
    • Runge-Kutta-Nystrom-Generalized (RKNG) methods
