Hi Zakaria,
I had such an issue before, and in my case, the problem was that the
calculation of the objective for some values used by the optimizer gave back a
non-finite result. In general, this might be because the objective function has
poles, and the calculation returns inf. Alternatively, there might be a
calculation error somewhere in the objective function's code resulting in a nan
value. I think that first, you need to determine more precisely what the
problem is in your case. You could try evaluating the objective at different
points (for instance, your initialization values) to see how it behaves.
I hope this helps!
