reports the computational running time in microsecond. MC algorithms were executed 1000 times on each of the instances and the total execution times have been presented. According to instance BFT MC-3 is 34.66% faster in average than other MC algorithms. Greedy algorithms, since they has been executed only once, convincingly outperformed MC algorithms. In terms of computational time Greedy-2 is 0.59%, and 14.20% faster than Greedy-1 and Greedy-3 repectively.
