WebSep 2, 2024 · To use the golden-section search method, we need to divide the search interval into two sub-intervals such that the ratio of the larger sub-interval to the smaller sub-interval is the same as the ratio of the entire interval to the larger sub-interval.

WebEquation (7.11) defines a parabola. Since the potential energy will be at a minimum. at equilibrium, the solution for displacement can be viewed as a one-dimensional optimization problem. Because this equation is so easy to differentiate, we can solve for the displacement as x = F∕k. For example, if k = 2 N∕cm and F = 5 N, x = 5N∕ (2 N/cm) =.
