Builds and returns the multi-objective DTLZ2 test problem.

The DTLZ2 test problem is defined as follows:

Minimize *
f[1](X) = (1 + g(XM)) * cos(x[1] * pi/2) * cos(x[2] * pi/2) * ... * cos(x[M-2] * pi/2) * cos(x[M-1] * pi/2)*

Minimize *
f[2](X) = (1 + g(XM)) * cos(x[1] * pi/2) * cos(x[2] * pi/2) * ... * cos(x[M-2] * pi/2) * sin(x[M-1] * pi/2)*

Minimize *
f[3](X) = (1 + g(XM)) * cos(x[1] * pi/2) * cos(x[2] * pi/2) * ... * sin(x[M-2] * pi/2)*

*...*

Minimize *
f[M-1](X) = (1 + g(XM)) * cos(x[1] * pi/2) * sin(x[2] * pi/2)*

Minimize *
f[M](X) = (1 + g(XM)) * sin(x[1] * pi/2)*

with *0 <= x[i] <= 1*, for *i=1,2,...,n*

where *
g(XM) = sum{x[i] in XM} {(x[i] - 0.5)^2}*
