AB - This paper shows a practical application of genetic algo-
rithms (GAs) for compensating the local magnetic perturbation 
produced by a ship, while moving in the earth's magnetic field. The 
compensation is achieved by modifying the number of turns and the current
magnitude across the so-called degaussing coils distributed along the
ship. A GA scheme for automatic optimisation of these parameters is
used. A new objective-function strategy, called a boundary method, is
proposed. It is shown that the convergence of the GA is greatly 
improved when the new objective function is used. Different selection
mechanisms, objective function strategies, and scaled methods are 
revised in this paper. The results show that GAs can be efficiently used to
reduce drastically the magnetic field levels of real practical ships.
