WebOptimizing a function¶. First, let’s start by optimizing the sphere function. Recall that the minima of this function can be located at f(0,0..,0) with a value of 0.In case you don’t remember the characteristics of a given function, simply call help().. For now let’s just set some arbitrary parameters in our optimizers. Web3. Sphere is a level set of the function F ( x, y, z) = x 2 + y 2 + z 2. For example, F ( x, y, z) = 1 corresponds to the sphere of the radius 1. Being a 2-dimensional object one can locally re-parametrize it with two independent coordinates, for example in the top semi-sphere, simply by x, y, from which z = 1 − x 2 − y 2. Share.
