The archive IB_eps.zip containts the approximation sets of DEMO SP2 and SPEA2
for the problems DTLZ and WFG. 

The files in the archive containing the approximation sets have the form 
X.Y.Z, where:

- X stands for the problem:
	DTLZ1
	DTLZ2
	DTLZ3
	DTLZ4
	DTLZ5
	DTLZ6
	DTLZ7
	WFG1
	WFG2
	WFG3
	WFG4
	WFG5
	WFG6
	WFG7
	WFG8
	WFG9
	
- Y stands for the algorithm: 
	demo_sp2
	spea2
	
- Z denotes the the number of objectives:
	m2 = 2 objectives
	m3 = 3 objectives
	m4 = 4 objectives

In all experiments, the population size was set to 100 and 300 generations were
evolved. Each algorithm was run 30 times on each problem.
