Visualizing a Simple Saddle Point Algorithm in MATLAB 2

Posted by Doug Hull,

There are lots of places in optimization and game theory where you would want to identify a saddle point on a two-dimensional surface. In this example we find and visualize the saddle point of a surface. We are trying to maximize the value of the surface by our choice in one dimension and trying to minimize it by our choice in the other dimension. Once we find this saddle point, we have found the optimal choice in each dimension.
