Absolute value equations (AVEs), characterised by the inclusion of absolute value functions in the variables, present inherently non‐smooth and computationally challenging problems that are often ...

We consider multigrid iterative methods for the solution of electromagnetic scattering for dielectric materials. We show convergence of the iteration using coarse grids which are two to four times ...

If the SINGLE option is not used, PROC MODEL computes values that simultaneously satisfy the model equations for the variables named in the SOLVE statement. PROC MODEL provides three iterative methods ...

where Z is a matrix of the independent variables, is a vector of the parameters, is the error vector, and F is a function of the independent variables and the ...

In my previous article, I outlined the planning stages that are performed during an XP project, with a particular emphasis on the upfront planning that is ignored in many “XP” projects. This month I ...
