Write a paper about Variable ordering and constraint propagation for constrained Lexicographic Preference Trees , it similar to Variable ordering and constraint propagation for constrained CP-net expect the instructor of LP tree is a bit different than CP-net . I want detail and experiment as well as the result as it showed in the reference ill attach .
