Golden-section search

The golden-section search is a technique for finding an extremum (minimum or maximum) of a function inside a specified interval.

The method operates by successively narrowing the range of values on the specified interval, which makes it relatively slow, but very robust. The technique derives its name from the fact that the algorithm maintains the function values for four points whose three interval widths are in the ratio 2-φ:2φ-3:2-φ where φ is the golden ratio. These ratios are maintained for each iteration and are maximally efficient.

The min_bound and max_bound arguments define values that bracket the expected minimum. The init_estimate argument is the initial estimate of the minimum that is required to be larger than min_bound and smaller than max_bound.
