Hi Qi Cheng,
NOX does support both function (left) and solution (right) scaling. The following unit tests demonstrate the capability:

Dear Sir or Madam,
I would like to use the nonlinear Nox solvers to solve nonlinear systems. To address the case of ill-conditioned nonlinear systems, other software allow prescribing scaling factors both for the solution vector and for the residual vector. Is there a similar option for Nox and if not, is something planned in this matter?
