[Ipopt] Solution of primal variables at each iteration

[stefan at vigerske.de]

Hi,

in intermediate_solution you get an IpoptData object that gives you a lot of information about the current Ipopt status.
With IpoptData::curr() you should get the current iterate, which should also contain the primal values.
The documentation at
http://www.coin-or.org/Doxygen/Ipopt/class_ipopt_1_1_ipopt_data.html
should be helpful.

Hi, 
  
     Is there a way by which I can know the solution of the primal variables at each iteration for Ipopt? I am using intermediate_callback method to get the interation index and the objective value - but would also like to get the primal variable values at  
each iteration.
