👉 In computer science and mathematics, "toppiece" is a concept used in the context of computer graphics. It refers to a piecewise linear function that can be represented by an equation with one or more variables. The toppiece principle states that if a function f(x) has a local minimum at x = a, then it must also have a global minimum at x = b for some values of a and b. This is because the derivative of f(x) at x = a must be zero
