|---|---|
| class  | BaseSecantSolverBase class for all bracketing Secant-based methods for root-finding
 (approximating a zero of a univariate real function). | 
| class  | BracketingNthOrderBrentSolverThis class implements a modification of the  Brent algorithm. | 
| class  | IllinoisSolverImplements the Illinois method for root-finding (approximating
 a zero of a univariate real function). | 
| class  | PegasusSolverImplements the Pegasus method for root-finding (approximating
 a zero of a univariate real function). | 
| class  | RegulaFalsiSolverImplements the Regula Falsi or False position method for
 root-finding (approximating a zero of a univariate real function). |
