gradient and jacobian

[dinesh286]

How gradient and jacobian is computed in PSOPT to supply for IPOPT. I have gone through the example code, garadient of jacobian computation are not computed.

Hello

The gradient and Jacobian used by the NLP solver are computed by the library Adol-C by default, or they are computed by finite differences (gradient) or sparse finite differences (Jacobian). The code for the finite differences is in file derivatives.cxx.

The code to compute the derivatives using Adol-c for IPOPT is included in file IPOPT_interface.cxx.
