Hybridization of Adaptive Differential Evolution with an Expensive Local Search Method

Table 3

Experimental results of SDENS, DASA, and DEELS on 10 test instances of 1000 variables with FES. Best, median, mean, and std. dev. of the function error values obtained over 25 runs.

Test instance	Best			Median			Mean			Std. dev.
	SDENS	DASA	DEELS	SDENS	DASA	DEELS	SDENS	DASA	DEELS	SDENS	DASA	DEELS
−	6	4		7	5		7	5		5	3
+	4	6		3	5		3	5		5	7

“−,” “+,” and “” denote that the performance of the SDENS and DASA algorithms is worse than, better than, and similar to that of DEELS, respectively.
