We primarily report results on two problem instances, both with the geometry illustrated in Figure 1. The smaller problem has 10,008 members, and the analysis takes approximately 2.5 seconds on a fairly high-end server (a Dell PowerEdge 1750 server with dual 3.2GHz Xeon processors and 4 GB memory). Although 2.5 seconds is not all that long in absolute term s, it is several orders of magnitude longer than might be expected for a “typical” fitness evaluation function in a GA.
