Detailed Description

multi-objective problem ELLIBase

The unrotated base problem of ELLI1

\[ f_1(x) = \frac{1}{a^2*n}\sum_{i=1}^{n}(a^{2{}\frac{i-1}{n-1}}*x_i^2) \]

\[ f_2(x) = \frac{1}{a^2*n}\sum_{i=1}^{n}(a^{2{}\frac{i-1}{n-1}}*(x_i-2)^2) \]

where usually $n = 10$ and $ a=1000 $

bool ELLIBase::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

Reimplemented from ObjectiveFunctionVS< double >.
