A hypothetical management science problem requires us to find the cheapest "supercircuit" in a graph. Three algorithms are available: Algorithm 1, Algorithm 2, and Algorithm 3.Algorithm 3 never produces a supercircuit that is off by more than 10% from the cheapest supercircuit. The amount of time that it takes to carry out Algorithm 3 is: 1 second for a graph with 5 or less vertices, 30 seconds for a graph with 6 vertices, 
for a graph with 7 vertices, and so on, increasing by 10 seconds every time we add a vertex (from 7 vertices on). Algorithm 3 is
