- f(x) > X$ a solution existence decision problem satisfying
- Size where x is permutation, subset, etc. not fully searchable
- When a greedy algorithm to find max f(x) cannot be thought of, it is easier to use the existence of solutions that satisfy f(x)>X, since it is not limited to the largest solution.
Let’s use a “beat to the answer” type of bifurcation search - ARMERIA
