深藍處代表「AΔB」 排容原理(inclusion–exclusion principle) 數個集合中,若要找到其聯集基數,可用反覆扣除交集、再加回反覆扣除的交集求得。 一、兩個集合的排容 將兩集合 A、B 相加後,扣除重複計算的交集部分,可得聯集「A∪B」,即「(|A∪B|)=(|A|+|B|)–(|A
|A∪B|=|A|+|B|−|A∩B| Inclusion-exclusion principle It is a fact of set algebra, called the principle of duality, that the dual of an identity is also an identity, where the dual of an identity can be obtained by replacing each occurrence of ∪, ∩, U, and ∅ in the ident...
The method is based on molecular fragmentation and allows a range-specified repartitioning of intramolecular (and potentially intermolecular) interactions where noncovalent interactions are selectively assembled using a piece-wise reconstruction based on a set-theoretic inclusion-exclusion principle generalization...

For the analysis, the SetMethods package of R was used [66,89]. For the calibration of the conditions and the outcome, the 95th percentile (total inclusion), the 5th percentile (total exclusion) and the mean (maximum ambiguity) were used. Four cases with a membership of 0.5 (Warsaw, Mil...
Other common notations related to set theory include , which is used to denote the set of maps from to where and are arbitrary sets. For example, an element of would be a map from the natural numbers to the set . Call such a function , then , , etc., are elements of , so call ...

In this section we explore an important graph theory problem. A problem that is very closely related to this was one of the first problems shown to be P-complete. There are many other graph problems that are known to be P-complete, and this one has a similar flavor to a number of tho...
