This paper presents the study of bismuth-doped yttrium iron garnets with composition Y<sub>3-x</sub>Bi<sub>x</sub>Fe<sub>5</sub>O<sub>12</sub> (Bi: YIG) prepared by sintrating of metal oxides for various sintrating conditions (times, temperatures, etc.). The structure of the samples was characterized by XRD patterns. The spectra, obtained by LIB (Laser Induced Breakdown) method that is based on the interaction of high power laser beam with studied medium, are also presented. Breakdown and following ablation were induced on the sample surface in air by focusing mode-locked Nd: YAP laser radiation. The laser-induced spectra for various bismuth-donated samples and metal oxides are compared.
Genetic Algorithm uses principles of evolution of organisms in nature to solve optimization problems. It is called
'genetic' because its operators are based on simplified concepts of population genetics. Evolution in the context of the
numerical methods is represented by the evolution of artificial organisms whose genotypes encode possible solutions to
