DOI: 10.1007/s11075-018-0485-3

Abstract: As is well-known, Jacobian smoothing method is a popular one to solve nonlinear complementarity problems, in which the Jacobian consistency is stressed. By investigating an element of related functions’ B-differential, a smoothing Levenberg-Marquardt(LM) method is… read more here.

DOI: 10.1007/s40314-020-01199-3

Abstract: In this work, we prove the quadratic convergence of the Levenberg–Marquardt method for the inverse problem of identifying a Robin coefficient for the Stokes system, where we suppose that this parameter is piecewise constant on… read more here.

DOI: 10.1080/02331934.2018.1435655

Abstract: Abstract A modified Levenberg–Marquardt method for solving singular systems of nonlinear equations was proposed by Fan [J Comput Appl Math. 2003;21;625–636]. Using trust region techniques, the global and quadratic convergence of the method were proved.… read more here.

DOI: 10.21136/am.2021.0064-20

Abstract: In this paper, we propose a smoothing Levenberg-Marquardt method for the symmetric cone complementarity problem. Based on a smoothing function, we turn this problem into a system of nonlinear equations and then solve the equations… read more here.
