Khare et al. (2015) describe an improved method for sampling for the method of morris.

I'm currently looking into this, implementing it should not be too hard.
(Was not really happy with the uniformity of my optimized samples)

If I understand it correctly, the main improvement is that you ensure that the first points of the trajectories are uniformly distributed across parameters.
(Isn't that the same as Latin Hypercube sampling?)

The rest of the method in the paper is what we call "brute force optimization" in SALib. I expect to work on this tomorrow.

FYI: Original (MATLAB) code can be found here:
