Corresponds to ideal optimum value | The optimal curve is the curve on the contour plot that corresponds to the ideal optimum value. | ||
Defective springs example | For the defective springs data, we search for the Y = 100 contour curve. As determined in the steepest ascent/descent section, the Y = 90 curve is immediately outside the (+, +) point. The next curve to the right is the Y = 95 curve, and the next curve beyond that is the Y = 100 curve. This is the optimal response curve. |
