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. Some useful packages for global optimization are OpenOpt, IPOPT, PyGMO and PyEvolve. Mar 22, 2012 · Using calculus (first, second deriv., etc) 2. Suppose f (x) = (x^3) − (6x^2) +9x defined on [0, 2]. Find the values of x that maximize and minimize f (x). Also find the maximum and minimum values of f (x). 3. Suppose f (x) = (x^3) − (6x^2) defined on [2, 5].

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.

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.
