the main purpose of this article is to increase the efficiency of the least squares method in numerical solution of ill-posed functional and physical equations. determining the least squares of a given function in an arbitrary set is often an ill-posed problem. in this article, by defining artificial constraint and using lagrange multipliers method, the attempt is to turn -dimensional least squ...

Continuous conformalmaps are typically approximated numerically using a trianglemeshwhich discretizes the plane. Computing a conformal map subject to user-provided constraints then reduces to a sparse linear system, minimizing a quadratic ‘conformal energy’.We address themore general case of non-triangular elements, and provide a complete analysis of the casewhere the plane is discretized using...

recently, in order to increase the efficiency of least squares method in numerical solution of ill-posed problems, the chain least squares method is presented in a recurrent process by babolian et al. despite the fact that the given method has many advantages in terms of accuracy and stability, it does not have any stopping criterion and has high computational cost. in this article, the attempt...
