ASP is optimized for combinatorial problems. Basically, you list the parts that are variable, and the constraints, the answers are given by the solver. Have a look at the documentation[0]. Here is an example:

    % Each shift needs a nurse).
    1 { shift_nurse(Shift, Nurse): nurse(Nurse) } 1 :- shift(shift).

    % It cannot be that a nurse does two shifts in a row.
    :- nurse(Nurse), shift_nurse(Shift1,Nurse),shift_nurse(Shift2,Nurse), Shift1 + 1 = Shift2.

You could have a look at the potassco suite[0]. It is a grounder and solver for Answer Set Programming (ASP). ASP is a form of Logic Programming.

It is research code (read very unpolished) but you can get inspiration from pyggp [1]. More specifically, the game_description_language module. I implemented pyggp for my masters thesis. It's a proof of concept and will be iterated upon.
