A Novel Model for Anomaly Detection in Network Traffic Based on Support Vector Machine and Clustering

Algorithm 2

PBB method [21].

	Input:, , , , , (used for terminating the algorithm)
Output: optimal solution of the BQP problem (12)
Step 1. Let i = 0.
Step 2. Calculate , where is the alternative BB step size, and .
Step 3. If , output as the optimal solution and terminate the algorithm. Otherwise, go to Step 4.
Step 4. Let and return to Step 2.
