PowellOptimizer(double rel,
double abs,
ConvergenceChecker<PointValuePair> checker)
Deprecated.
This constructor allows to specify a user-defined convergence checker,
in addition to the parameters that control the default convergence
checking procedure.

PowellOptimizer(double rel,
double abs,
double lineRel,
double lineAbs)
Deprecated.
Builds an instance with the default convergence checking procedure.

PowellOptimizer(double rel,
double abs,
double lineRel,
double lineAbs,
ConvergenceChecker<PointValuePair> checker)
Deprecated.
This constructor allows to specify a user-defined convergence checker,
in addition to the parameters that control the default convergence
checking procedure and the line search tolerances.
