DTLZ3 Function (family)
Description
Builds and returns the multi-objective DTLZ3 test problem. The formula
is very similar to the formula of DTLZ2, but it uses the g
function
of DTLZ1, which introduces a lot of local Pareto-optimal fronts. Thus, this
problems is well suited to check the ability of an optimizer to converge
to the global Pareto-optimal front.
The DTLZ3 test problem is defined as follows:
Minimize f1(x)=(1+g(xM))cos(x1π/2)cos(x2π/2)⋯cos(xM−2π/2)cos(xM−1π/2),
Minimize f2(x)=(1+g(xM))cos(x1π/2)cos(x2π/2)⋯cos(xM−2π/2)sin(xM−1π/2),
Minimize f3(x)=(1+g(xM))cos(x1π/2)cos(x2π/2)⋯sin(xM−2π/2),
⋮
Minimize fM−1(x)=(1+g(xM))cos(x1π/2)sin(x2π/2),
Minimize fM(x)=(1+g(xM))sin(x1π/2),
with 0≤xi≤1
, for i=1,2,…,n,
where g(xM)=100[∣xM∣+xi∈xM∑(xi−0.5)2−cos(20π(xi−0.5))]
