This paper analyzes least square problems over a noncompact Lie group, the symplectic group $\\Sp(2N,\\R)$, which can be used to assess the optimality of control over dynamical transformations in classical mechanics and quantum optics. The critical topology for minimizing the Frobenius distance from a target symplectic transformation is solved. It is shown that the critical points include a unique local minimum and a number of saddle points.
