WebTo minimize the function, we can instead follow the negative of the gradient, and thus go in the direction of steepest descent. This is gradient descent. Formally, if we start at a point x_0 x0 and move a positive distance \alpha α in the direction of the negative gradient, then our new and improved x_1 x1 will look like this: WebThis document describes graphical and algebraic ways to minimize boolean functions.
