Except for the fact that we are right. There are two algorithms or mechanical explanations for any function.

And algorithm has nothing to do with how a model gives predictions. An algorithm is a way to solve a problem. A function or equation is also completely different. Yes, you have post some examples or sorting, but they are not functions!! The function is, for each value x of the set, s(x) = p, where P is the position. All your sort functions give the same P to the same x, so they're the same function. The way you solve it is irrelevant.

Also, PizzaPlanet example about x^2 and x^4 is ridiculous. They only have the same values for 0,1 and -1, not for the entire domain of the function. The equation that describes a planet movement is f(t) = c, being c a coordinate (respect to the sun, for example) and t the moment of time. If two functions predict the same values for c with the same values for t, then they're the same function. With Newton's and Einstein's theories, they predict very close values, but NOT THE SAME. Einstein's equations are more accurate, then his theory is more correct or more accurate. But they're not the same theory because they don't predict the same exact values!!!
