The area of magnetism offers a wealth of possibilities to study different algorithmic approaches. The reason is the diversity of different forms which can be used to describe magnetic samples. One can start from the most simple Ising-like system which, being of physical origin, became an inspiration for many models in a various areas of science and the formulation of which fits ideally the earliest representations of genetic algorithms. The recent problems concern elaborate molecular structures, like eg. spin glasses where the character of interaction between the spins of the same type may be different depending on some random variable or mixed alloys which can have different stoichiometry or structure and therefore present visibly distinct magnetic characteristics. In this paper we will deal with the mixed magnetic ternary alloy - an analog of prussian blue. Some results concerning the physical conclusions coming from applying the evolutionary computation to analyse this material have already been published and here the attention will be paid to the influence of parameter change on the efficiency of procedure.
