Steve,

More information is as follows:

   - No. of unknowns: 3. These are the values of the pan angle, the tile
   angle and the focal length in meters to be optimized.
   - Differentiable: Yes.
   - Analytical Derivative: Not available.
   - Local Optimum sufficient: Yes.
   - Non Linear constraints: Yes. The number of constraints increases with
   the number of targets to be imaged. That being said, I want to start off
   with a very simple scenario where there's 1 target, and 1 camera.

Thank you,

Akshay.
