scipy.optimize.brute calls a algorithm after its own search : fmin is default. To respect ranges, I set "finish" argument to None. scipy.optimize.brute(f, myranges,Ns=2,finish=None) I didn't read the documentation enough... Anyway, maybe it would be a good idea to set default algorithm to a constrained algorithm instead of fmin ...

Background. How animals regulate organ size and proportion is an enduring question in biology. Regeneration is a particularly interesting context to ask this question, as the organ must regenerate anew in the context of an already developed organism.

Thus, for a function like sin (0.5 * x), it will start at the lowest point that the brute function found (-pi/2) and continue from there, finding -pi to be the (closest-by) global minimum. The solution is simple: res = optimize.brute(g, (ranges,), finish=None) will give what you want. model is optimally scaled to maximize ll before calculation.

Another available (but much less efficient) global optimizer is scipy.optimize.brute() (brute force optimization on a grid). More efficient algorithms for different classes of global optimization problems exist, but this is out of the scope of scipy.

- As documented, scipy.optimize.brute returns -- among others -- the "function value at minimum". Unexpectedly, but still documented, this value is always of integer type. So, for example if x_min was identified by the brute force optimization function to be the minimum location and f(x_min) really is 4.8, then fval is returned as 4.
