[Coin-ipopt] Handle the problem without using automatic differentiation

[Zhongzhou Chen]

Hi, all:

 

I am trying to solve a large scale optimization problem. Automatic
differentiation is highly impossible due to the model structure. 

Is there an option to allow Ipopt to calculate the Jacobin and Hessian using
finite difference? 

Should I try other software, like Conopt?  

 

Thanks,

 

David
