Improved Genetic Algorithm for Distribution System Performance Analysis by Taking Advantage of Essential Spanning Trees

Table 6

Comparing average CPU time and maximum occurrence rates in 25 runs obtained with the full 37-switch pool and the essential switches for the 32-bus test system.

Gen	N	Full (37) switch pool		Reduced switch pool from selected essential switches
		Average CPU time (seconds)	Maximum Occurrence rate (percent)	Average CPU time (seconds)	Max Occurrence rate (percent)
