In this note, we reinterpret a discontinuous Galerkin method originally developed by Huand Shu [1] (see also [2]) for solving Hamilton-Jacobi equations. By this reinterpretation,numerical solutions will automatically satisfy the curl-free property of the exact solutionsinside each element. This new reinterpretation allows a method of lines formulation, whichrenders a more na...

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...
