WebSep 17, 2024 · In numerical analysis, the shooting method reduces a boundary value problem to an initial value problem. It is a popular method for the solution of two-point boundary value problems. If the problem is first defined by y=f (x); y (x0)=a and $y (X_1)$, it is transformed into the initial problem y’ =z (x) and z’ (x) = f (x) with some initial values.
