Detailed Description

multi-objective problem CIGTABBase

The unrotated base problem of CIGTAB1

$f_1(x) = \frac{1}{a^2*n} [x_1^2 + \sum_{i=2}^{n-1}a*x_i^2 + a^2*x_n^2]$

$f_2(x) = \frac{1}{a^2*n} [(x_1-2)^2+ \sum_{i=2}^{n-1}a*(x_i-2)^2 + a^2* (x_n-2)^2]$

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

bool CIGTABBase::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 >.
