Grid Points Example

For a three factor problem, stopping at sixteenths (17 levels), the number of points searched is 17*17*17=4913. For nine factors, stopping at halves (3 levels), the number of points searched is 19,683.

Note that the time it takes to search a grid of any size is highly dependent on the processor in your computer and the amount of RAM (Random Access Memory) that is installed in your computer.
