Summary, etc. Performance of Self Amplifed Spontaneous Emission (SASE) operation for an X-ray Free-Electron Laser (FEL), is optimized by Multiple Objective Evolutionary Algorithms (MOEA). Different types of hybrid planar undulators are considered to achieve 0.5 Å ≤ λ<sub>FEL</sub> ≤ 1.5 Å wavelength range. This demand is regarded as a continuous optimization problem, and hence, an evolutionary algorithm is designed to find optimal FEL performance parameters. An encoding scheme comprising of undulator period (λ<sub>u</sub>) and undulator gap (g) is adopted here to find optimal values for saturation power (P<sub>sat</sub>) and λ<sub>FEL</sub> subject to several physical constraints on λ<sub>u</sub> and g such as the ratio of g/λ<sub>u</sub> and L<sub>sat</sub>. It is shown that MOEA gives optimal solutions for estimation of L<sub>sat</sub> with plausible P<sub>sat</sub> values.
