Detailed Description

multi-objective problem ZZJ07_F8

Multi objective problem with quadratic Pareto Set shape. The ZZJ07_F8 problem is given by:

\[ f_{1}(x)=\cos (\frac{\pi}{2}*x_1) \cos (\frac{\pi}{2}*x_2)(1+ g(x)) \]

\[ f_{2}(x)=\cos (\frac{\pi}{2}*x_1) \sin (\frac{\pi}{2}*x_2)(1+ g(x)) \]

\[ f_{3}(x)= \sin (\frac{\pi}{2}*x_1)(1+ g(x)) \]

where

\[ g(x)= \sum_{i=3}^{n} (x_i^2 - x_1)^2 \]

\[ 0 \leq x_i \leq 1 \]

and usually $ n=30 $

Member Function Documentation

bool ZZJ07_F8::nadirFitness ( std::vector< double > &  value  )  const [virtual]

If possible, this method returns (a bound on) the worst possible fitness.

For single objective optimization this information is rarely of any use, while for multi objective optimization a so-called nadir point is important for the computation of standard quality indicators like the hypervolume.

Parameters:
fitness component wise worst fitness
Returns:
true if a nadir point is known, false otherwise

unsigned int ZZJ07_F8::objectives (  )  const [virtual]

bool ZZJ07_F8::utopianFitness ( std::vector< double > &  value  )  const [virtual]

If possible, this method returns (a bound on) the best possible fitness.

For the single objective case the function should return the fitness in the global optimum. For the multi objective case this function should return a utopian point.

Parameters:
fitness component wise utopian fitness
Returns:
true if an utopian point is known, false otherwise
