Overview of course content, including an motivating problem for each of the modules. The lecture then covers 1-D and 2-D peak finding, using this problem to point out some issues involved in designing efficient algorithms.
The BFGS algorithm is slightly modified to work under situations where the number of unknowns are too large to fit the Hessian in memory, this is the well known limited memory BFGS or LBFGS. While BFGS uses an approximation to the full Hessian (that need to be stored), LBFGS only stores a set of vectors and calculates a reduced rank ...
Aug 20, 2017 · Minitab: The Gauss-Newton algorithm is the default for least squares estimation. R: The default non-linear least squares algorithm is the Gauss-Newton. Other options are plinear for the Golub-Pereyra algorithm (for partial LLS), or port for the nl2sol algorithm from the Port Library. Variations
Newton's method may also fail to converge on a root if the function has a local maximum or minimum that does not cross the x-axis. As an example, consider () = − + with initial guess =.In this case, Newton's method will be fooled by the function, which dips toward the x-axis but never crosses it in the vicinity of the initial guess.

The gauss-newton algorithm is applied to reconstruct a two-dimensional image of Electrical Impedance Tomography (EIT) using python program. The study aimed to determine the characteristics of body tissues either conductive or resistive properties through the tissue structure which is displayed in the form of images so we can distinguish between one tissue and another.
