Least cubic method
NettetFinally, we outline the simulation test carried out to measure the inchworm-like robot’s creeping gait. The results show that the motion path obtained by using the planning method proposed in this paper is the one with the least energy consumption by the robot among all the comparison paths. Nettet13. sep. 2016 · Compared with the commonly used least-square method, the least-cubic method was more useful for finding the center in asymmetric cases (i.e., nanorods) with high precision and accuracy.

You need to differentiate S with respect to each ak and set that expression equal to zero. This will give you 4 equations in the 4 ak s. Here is a typical one:
