WebJun 13, 2016 · In particular, gradient flow is a descent method, which means it always decreases the objective function: d dt f(Xt) = ∇f(Xt), ˙Xt = − ‖∇f(Xt)‖2 ≤ 0. This is a natural property for optimization: Since our goal is to minimize f, it makes sense to decrease f as much as possible at each time. pool ring toss games for kids

WebIn order to retain a gradient slope value of 3.72 we would need to adjust the flow rate to 1.6 mL / min. Gradient slope G s (20 minute gradient, 150 x 4.6mm column) = 1.7 x 70 / 1.6 x 20 = 3.72. So lets see what the original monograph method would look like with a 20 minute gradient and a flow rate of 1.6 mL/min.
