## Brent’s methods

### BrentOpt

A minimization algorithm combining parabolic interpolation and the golden-section method. It has the reliability of the golden-section method, but can be faster thanks to the parabolic interpolation steps.

a function of one variable”, *Algorithms for minimization without
derivatives*, Richard P. Brent, 1973, Prentice-Hall.

### BrentRoot

A root-finding algorithm combining the bisection method, the secant method and inverse quadratic interpolation. It has the reliability of bisection but it can be as quick as some of the less-reliable methods.
