Optimization method, guided by mathematical principles, reasonably arranges experiments, and finds the optimal scheme in production and scientific experiments as soon as possible with as few experiments as possible. That is, the optimization method.

take for example

For example, to trial-produce a new material, it is necessary to add some raw materials to enhance its strength, so there is a question of how much to add. If you add more, you can't do less, only it is completely appropriate. For example, we estimate that the dosage per ton is between 1g and 1000g, so we can simplify the number of experiments with the golden section rule, instead of doing 100g from1000g. We use a graduated note to represent 1g to 100g. Draw a vertical line where you find 6 18 (1000 * 0.618) grams on the paper, do an experiment, and then fold the paper in half to find the symmetry point 382 (618 * 0.6) Then fold it in half and find the symmetry point 236(382*0.6 18) of 382 to do the experiment, so as to find the best value back and forth.
