"WebApr 28, 2016 · You can't tell fminsearch to consider only integers. The algorithm it uses is not suitable for discrete optimization, which in general is much harder than continuous optimization. If there are only relatively few plausible values for your integer parameter (s), you could just loop over them all, but that might be too expensive. " - Fminsearch in python
