WebOct 12, 2024 · Brent’s method is an optimization algorithm that combines a bisecting algorithm (Dekker’s method) and inverse quadratic interpolation. It can be used for constrained and unconstrained univariate function optimization. The Brent-Dekker method is an extension of the bisection method. WebThe Brent function is conveniently accessed through a using statement (noting sub-namespace ::tools ). The search minimum and maximum are chosen as -4 to 4/3 (as in the Wikipedia example). Tip S A Stage (reference 6) reports that the Brent algorithm is slow to start, but fast to converge, so choosing a tight min-max range is good.
