Hi Hong, Thanks for the explanation!
If I have a cost function consisting of an L2 norm of the difference of a TS-solution and some reference along with some constraints (say bounds, L1-sparsity, total variation etc), would I provide a routine for gradient evaluation of only the L2 norm (where TAO would take care of the constraints) or do I also have to take the constraints into account (since I'd also have to differentiate the regularizers) ?
