Is there a way to limit the search space to solutions that have a maximum of n constants?
For example, if n is set to 3, the following solutions would be allowed:
y = 1-pow(0.924332,xx)
y = 1-pow(0.927465,xx+0.446301)
But the one below would not be allowed:
y = 1-pow(0.904524,x*((-1.28246)+x)+1.60574)
