Methods to Find Overlapping Communities

Community detection in graphs http://arxiv.org/abs/0906.0612通常の手法は,1 頂点はちょうど 1 つのコミュニティに所属する.そうではなく,1 頂点が複数のコミュニティに所属し得るようなコミュニティ列挙の手法.

pow_mod, inverse の速度

ベンチマークコード 適当.g++ -O2.標準入力は適当に10とか入れてる. const ll MOD = 1000000009; const int N = 2000000; int main() { int a; scanf("%d", &a); ll t = a; for (int k = 1; k <= N; ++k) { t = inverse(t, MOD) * k % MOD; } printf("%ll…
