We tried two problems - the 127 city problem and the 150 city problem. We can start seeing the difference in time and quality at this stage. The IGA does better, both in running time and tour length. Fig 4 shows the best tours on the 150 city problem. There is a marked increase in the number of crossings for the tour produced by the GA when compared to the IGA tour. Since the number of crossings correlates with tour length the GA's tour is longer than IGA's tour. Results from the 127 city problem are similar.
