This convergence to the appropriate answer ( ef{e6}) quite very slowly because of the $ $ $ to have size must be selected au small will result in the stability and convergence.
This method converges to the solution of ( ref {e6}) rather slow because $ tau $ be selected to be small, it will contribute to the stability and convergence.
This method is convergent to the optimum of (- ref {E6}) quite slow because tau $$, to choose to have small size, it will result in this method is stable and convergent .
