Encyclopedia > Shooting method

In numerical analysis, the shooting method is a method for solving a boundary value problem by reducing it to the solution of an initial value problem. The following exposition may be clarified by this illustration of the shooting method.


For a boundary value problem of a second-order ordinary differential equation, the method is stated as follows. Let

be the boundary value problem. Let y(t1; a) denote the solution of the initial value problem

Define the function F(a) as the difference between y(t1; a) and the specified boundary value y1.

If the boundary value problem has a solution, then F has a root, and that root is just the value of y'(t0) which yields a solution y(t) of the boundary value problem.


The usual methods for finding roots may be employed here, such as the bisection method or Newton's method.
