Applying these algorithms to a long-span continuous rigid frame bridge, the differences of optimization focuses and the differences in optimization effects of various algorithms are compared. The four criteria of the mean square error, the maximum value of the non-diagonal MAC matrix and the information matrix of the Fisher information matrix and the condition number of the modal matrix are used to analyze the optimization effect of the sensor arrangement. Finally, the four evaluation criteria are combined The mean value is established to establish a comprehensive evaluation system of the result of the optimization algorithm. The analysis results show that in order to optimize the layout of sensors, we must compare and contrast the results of different optimization algorithms with a variety of criteria, and choose the one with the highest comprehensive score.
