Powell's dog leg method, also called Powell's hybrid method, is an iterative optimisation algorithm for the solution of non-linear least squares problems, introduced in 1970 by Michael J. D. Powell. Similarly to the Levenberg–Marquardt algorithm, it combines the Gauss–Newton algorithm with … See more Given a least squares problem in the form with $${\displaystyle f_{i}:\mathbb {R} ^{n}\to \mathbb {R} }$$, Powell's dog leg method finds the optimal point See more • Lourakis, M.L.A.; Argyros, A.A.
