Hi all,
if anyone is interested - here is one more constrained NLP/NSP solver 
(OpenOpt ralg). 1st derivatives df, dc, dh can be handled as well.

Currently it has no difference of providing some constraints (c[i]<=0, 
h[j]=0) or single: max_i,j_(c[i], abs(h[j]))=0.
But in future I intend to add a little bit better constraints handling 
in case of several funcs.

See the NLP example published some days ago with ralg:

Regards, D.
