Definition: "Besmooth" is a mathematical term that refers to a function or a set of functions that are minimized or extremized. It can be defined as a function that is smooth in some sense, meaning it has no discontinuities or corners and its derivative is continuous. This means that the function's value at any point is equal to its own derivative evaluated at that point. In other words, "besmooth" refers to a function or set of functions that are easy to manipulate and
