WebBrent's method for univariate function optimization. Example from brent_search import brent def func ( x, s ): return ( x - s) **2 - 0.8 r = brent ( lambda x: func ( x, 0 ), -10, 10 ) print ( r) The output should be ( 0.0, -0.8, 6) Install From … WebBrent’s method combines root bracketing, interval bisection, and inverse quadratic interpolation. It is sometimes known as the van Wijngaarden-Dekker-Brent method. Brent …

WebThe combination of these steps produces a simultaneously minmax optimal method with guarantees similar to interpolation based methods for smooth functions, and, in practice will outperform both the bisection method and interpolation based methods under both smooth and non-smooth functions.

Python comes with a module that provides the base for defining Abstract Base classes (ABC) and that module name is ABC. ABC works by decorating methods of the base class as abstract and then registering concrete classes as implementations of the abstract base. tece news
