Scripts and Functions: Using R to Implement the Golden Section Search Method for Numerical Optimization

The Chemical Statistician

In an earlier post, I introduced the golden section search method – a modification of the bisection method for numerical optimization that saves computation time by using the golden ratio to set its test points.  This post contains the R function that implements this method, the R functions that contain the 3 functions that were minimized by this method, and the R script that ran the minimization.

I learned some new R functions while learning this new algorithm.

– the curve() function for plotting curves

– the cat() function for concatenating strings and variables and, hence, for printing debugging statements
