模差逻辑很难
Modular difference logic is hard
摘要:
关于机器算术,我们感兴趣的是形式为x + k \leq y + k '的约束系统。在整数上,这类系统的可满足性问题是多项式时间。如果我们把注意力限制在固定模N的剩余上,问题就变成NP完全的。
英文摘要:
In connection with machine arithmetic, we are interested in systems of constraints of the form x + k \leq y + k'. Over integers, the satisfiability problem for such systems is polynomial time. The problem becomes NP complete if we restrict attention to the residues for a fixed modulus N.
