The accuracy of thermal parameters, which are one of the important conditions to study the problem of temperature control and crack prevention of concrete, directly influence the calculation of concrete temperature and stress field. Based on basic genetic algorithm, the FORTRAN procedure was programmed after improving its defects. According to a project, the temperature test was carried out in one of sections of a prototype concrete structure, and the measured temperature dates were obtained. Based on the improved genetic algorithm and the measured temperature dates, the thermal parameters of concrete were obtained after back analysis, and the calculated and measured values were compared. The results show that the improved genetic algorithm provides a effective way for back analysis of concrete temperature field.

Background: In order to make up for the shortcomings of the traditional algorithm, Min-Min and Max-Min algorithm are combined on the basis of the traditional genetic algorithm. Methods: In this paper, a new cloud computing task scheduling algorithm is proposed, which introduces Min-Min and Max-Min algorithm to generate initialization population, and selects task completion time and load balancing as double fitness functions, which improves the quality of initialization population, algorithm search ability and convergence speed. Results: The simulation results show that the algorithm is superior to the traditional genetic algorithm and is an effective cloud computing task scheduling algorithm. Conclusion: Finally, this paper proposes the possibility of the fusion of the two quadratively improved algorithms and completes the preliminary fusion of the algorithm, but the simulation results of the new algorithm are not ideal and need to be further studied.
