Hello,

I would like to run simple unconstrained algorithms (like gradient descent, trust-regions etc.) and have the solver return the following quantities:

the function value at each iterate visited by the algorithm
the gradient norm at each iterate
the time spent in each iteration
a list of all the iterates x_k
Is this currently supported ? I wasn't able to find this in the documentation.

Thanks a lot
Florentin

This sounds like the "trace"? If you write Optim.trace(your_results) does it have the information you are looking for?
