Experimental results by PMPSO on each instance.

	Average deviation (%)	Best deviation (%)	Worst deviation (%)	no. best/no. instance	Percentage of hits (%)
J30	0.01	0	0.20	465/480	96.88
J60	0.22	0	0.67	385/480	80.21
J90	0.31	0	1.1	370/480	77.08
J120	0.98	0	2.5	251/600	41.83

hit means finding the best known solution
