Fast Two-Dimensional Optimization
Dear R Helpers,
I have attempted "optim" function to solve a two-dimensional optimization
problem. It took around 25 second to complete the procedure.
However, I want to reduce the computation time: less than 7 second. Is there
any optimization function in R which is very rapid?
Best Regards,
Wonsang
