Collective Intelligence for Network Control

It is also interesting to note that when initialising the network with a large number of time steps, a combination shortcut / blocking problem occurs. The ABC system has 'overlearnt' one particular route, and when it becomes congested, it does not find the other route. Adding noise however, largely overcomes this problem. (Compare the last two numbers). Other experiments were performed on the network of Figure 26. Here I expected the fixed routing scheme to perform worse. The capacities of nodes 3, 4 and 5 are now 30 calls each, and again calls are only made from node 1 to 2 or from 2 to 1. The other settings remained the same. All experiments have been performed five times with different call patterns for every experiment. The results were this time:
