Ok, so you’ve successfully reduced the problem space from 2^n to 2^(kn) + 2^(n-kn) , where k is the ratio of options in the two categories. That’s better, but

Ok, so you’ve successfully reduced the problem space from 2^n to 2^(kn) + 2^(n-kn) , where k is the ratio of options in the two categories. That’s better, but still clearly exponential growth.
