WebMathematical optimization deals with the problem of finding numerically minimums (or maximums or zeros) of a function. In this context, the function is called cost function, or objective function, or energy. WebPython’s reduce () is a function that implements a mathematical technique called folding or reduction. reduce () is useful when you need to apply a function to an iterable and reduce it to a single cumulative value. Python’s reduce () is popular among developers with a functional programming background, but Python has more to offer.
