Hill Climbing (finding local min and max)

Catherine Winfield

Description: This code uses hill climbing to determine local min and max. In another version of the script also included you can evaluate the surface for all its points and assigns a color based on its min and max. You could use this method as well to determine the global min and max of the surfaces.

Pseudo Code:

The min max code:

‘Get the Surface

‘Plot 100 Points on the surface

‘Evaluate each point for the min and max based upon the z value

‘Add a point at each local min and max

‘Get the Surface ‘Plot 100 Points on the surface ‘Evaluate each point for the min and max based upon the z value ‘Add a point at each local min and max

The color code:

‘Get the Surface

‘Point 100 Points on the surface

‘Add a point at every place on the grid

‘Assign a color to each point
