BICGSTAB, MINRES, GMRES, ORTHOMIN???

Hi,

just a little question; for a stokes solver,

In almost all the bibliographical FEM articles, I have seen that is mentioned always the GMRES and the BICGSTAB methods as solvers, but in another book I had found the algorithms Orthomin and Orthores, which I did not know them very well, but its algorithms are easy to implement.

Someone can tell me if they are a good alternative to the previous ones, and if they work for not non-symmetric problems?

Thank you very much,

Carlos
