`scipy.optimize.``golden`(func, args=(), brack=None, tol=1.4901161193847656e-08, full_output=0)

  Return the minimum of a function of one variable.

  Given a function of one variable and a possible bracketing interval, return the minimum of the function isolated to a fractional precision of tol.

  Parameters: | func : callable func(x,*args) Objective function to minimize. args : tuple, optional Additional arguments (if present), passed to func. brack : tuple, optional Triple (a,b,c), where (a<b<c) and func(b) < func(a),func(c). If bracket consists of two numbers (a, c), then they are assumed to be a starting interval for a downhill bracket search (see `bracket`); it doesn’t always mean that obtained solution will satisfy a<=x<=c. tol : float, optional x tolerance stop criterion full_output : bool, optional If True, return optional outputs.

  Notes

  Uses analog of bisection method to decrease the bracketed interval.
