Package org.orekit.control.indirect.adjoint.cost

This package provides routines to model the control cost in adjoint equations as in the Pontryagin Maximum Principle. The cost function (to be minimized) appears in the Hamiltonian and the maximization of the latter provides a relationship between adjoint variables and the optimal control law.
