“…To merge fruit counts from both sides, we compute the intersection of the connected components from both sides (Figure 6h). Then, we compute the total counts by summing up the counts from all the connected components, computing the intersection area among them (among 1, 2, ..., the total number of intersecting clusters) and adding/subtracting the weighted parts using the inclusion-exclusion principle (Andreescu & Feng, 2004; Figure 6i). This method is thoroughly evaluated in Section 6.5.…”

“…More generally, the number of derangements in various families of transitive permutation groups has been studied extensively in recent years. For more and detailed information on the derangement numbers !n, please refer to [1,2,12,13] and plenty of references therein. In [10], by studying the equation…”
