我還沒有100%的信心,但我給了一個例子,我試着簡化這裏。 我認爲這是最簡單的,如果你可以簡單地使用從0到n-1的整數都在同一集合中。
#include <iostream>
#include <boost/pending/disjoint_sets.hpp>
#include <vector>
typedef boost::disjoint_sets_with_storage<> Uf;
std::vector<pair<int,int>> same_set;
// fill the vector with number pairs between 0 and n-1 where
// n is the number of unique elements in the set
// ...
int n = ...; // n is the number of unique set elements
Uf union_find_set(n); // creates the structure with numbers 0 to n-1
// in seperate sets. -> one set is for 0, one set for 1, ...
for (auto same : same_set) {
union_find_set.union_set(same.first, same.second);
}
// union_find_set now contains sets with the numbers
// 0 to n-1 according to which sets should be combined
// given in the vector same_set.
// check whether two elements are in the same set, i.e. 0 and 2:
std::cout << union_find_set.find_set(0, 2);

我從來不喜歡這個實現。爲了我所有的需要,我使用我自己的實現使用列表和無序地圖。 – Arunmu
@Greg謝謝但不,它的界面不一樣 –
