A historical development of the (n+1)-point secant method

, 2007
Many finite-dimensional minimization problems and nonlinear equations can be solved using Secant Methods. In this thesis, we present a historical development of the (n + 1)-point Secant Method tracing its evolution back before Newton's Method.

A modified secant method for unconstrained minimization

, 1972
A gradient-secant algorithm for unconstrained optimization problems is presented. The algorithm uses Armijo gradient method iterations until it reaches a region where the Newton method is more efficient, and then switches over to a secant form of ...

Combination Of The Sequential Secant Method And Broyden's Method With Projected Updates

, 2015
We introduce a new algorithm for solving nonlinear simultaneous equations, which is a combination of the sequential secant method with Broyden's Quasi-Newton method with projected updates as introduced by Gay and Schnabel. The new algorithm has the order

Secant-Improved State Estimation Method for Moving Target Tracking Under Video Satellite

Aerospace
A video satellite has continuous imaging capabilities, which grants it great potential for tracking and monitoring moving targets. The Extended Kalman Filter (EKF) and Unscented Kalman Filter (UKF) are commonly used in the above process.
