增强几何匹配是$NP$完成的
Augmenting a Geometric Matching is $NP$-complete
摘要:
已知平面上的$2n$点,总是存在完美的直线不相交匹配。我们表明,它是$NP$ -完全的决定,如果部分匹配可以增加到一个完美的,通过减少从1-在3-SAT。这一结果也适用于双色匹配。
英文摘要:
Given $2n$ points in the plane, it is well-known that there always exists a perfect straight-line non-crossing matching. We show that it is $NP$-complete to decide if a partial matching can be augmented to a perfect one, via a reduction from 1-in-3-SAT. This result also holds for bichromatic matchings.
