disjoint subset 中文意思是什麼
disjoint subset
解釋
不相交子集-
The main idea is that randomly select two disjoint subsets of equal size out of instruction set and this selection is the watermark which is superimposed by changing the elements of one subset by adding a positive integer factor
在程序的指令集中隨機抽取兩個不相交的基數相等的子集，對特定子集的選取就是要嵌入的水印。改變程序使對應于某個子集的所有指令的出現次數都增加一個常數。
