Minimum() [1/2]

FunctionMinimum ROOT::Minuit2::FumiliBuilder::Minimum ( const MnFcn &  fMnFcn, const GradientCalculator &  fGradienCalculator, const MinimumSeed &  fMinimumSeed, const MnStrategy &  fMnStrategy, unsigned int  maxfcn, double  edmval  ) const

virtual

Class the member function calculating the Minimum and verifies the result depending on the strategy.

Parameters

fMnFcn	the function to be minimized.
fGradienCalculator	not used in Fumili.
fMinimumSeed	the seed generator.
fMnStrategy	the strategy describing the number of function calls allowed for Gradient calculations.
maxfcn	maximum number of function calls after which the calculation will be stopped even if it has not yet converged.
edmval	expected vertical distance to the Minimum.

Returns

Returns the function Minimum found.

Implements ROOT::Minuit2::MinimumBuilder.
