Figure 4
Performance of the GA-based optimization program on the XAFCA beamline. Lines a–e represent the normalized flux at the sample position, which was measured using the ionization chamber, corresponding to the best individual changes over generations. The initial flux from line a to line e decreases in order, which results in the increase of the number of generations needed for convergence. The initial fluxes and the generation numbers for completing optimization for each line are listed in the figure. |
