WebI Direct Single and Multiple Shooting solve equivalent NLPs, i.e. they have the same discretization errors. I Multiple shooting keeps the initial states of all shooting intervals as optimization variables, while single shooting eliminates all states by a forward simulation. I The Generalized Gauss-Newton method is advantageous in Web4.1. Shooting Method. Boundary-value problems are also ordinary differential equations—the difference is that our two constraints are at boundaries of the domain, rather than both being at the starting point. For example, consider the ODE. (4.1) y ′ ′ + x y ′ − x y = 2 x. with the boundary conditions y ( 0) = 1 and y ( 2) = 8. The ...
