条件偏好网络(CP网)提供了一个潜在的定性偏好的紧凑表示。许多关于CP-网的研究限制了对二元变量的严格偏好。我们扩展了以前的研究人员的工作,允许建模的偏好多值变量,其中一些偏好保持器可能是漠不关心的。我们展示了如何利用SAT求解器的力量来学习和推理这样的CP网络。我们还考虑了指数长翻转序列的可能性,表明为什么在实践中这是不太可能有问题的。
Conditional preference networks (CP-nets) offer a potentially compact representation of qualitative preferences. Much of the research on CP-nets limits attention to strict preferences over binary variables. We extend the work of previous researchers to allow modeling preferences over multi-valued variables over some of which the preference holder may be indifferent. We show how to leverage the power of SAT solvers to learn and reason with such CP-nets. We also consider the possibility of exponentially long flipping sequences, showing why in practice this is unlikely to be problematic.
