It is possible for Embed to terminate at a point that is not optimal. If X is the vector of n variables when Embed terminates (final values of the parameterUnknowns), then one of the following conditions must hold:

      X closely approximates a global optimum

      X closely approximates a local optimum, but not a global optimum

      X does not closely approximate even a local optimum

These statements apply in both Phase I and Phase II optimization.
