Abstract： Aiming at the distributed flexible job shop scheduling problem under dual resource constraints considering the influence of workpiece transportation time between factories and machines, a distributed flexible job shop scheduling problem (DFJSP) model with the optimization goal of minimizing completion time is established, and an improved mayfly algorithm (IMA) is proposed to solve it. Firstly, the mayfly position vector is discrete mapped to make it applicable to the scheduling problem. Secondly, three-layer coding rules of process, worker and machine is adopted, in which the factory selection is reflected by machine number, according to the characteristics of the model, a hybrid initialization strategy is designed to improve the population quality and diversity; Thirdly, an active time window decoding strategy considering transportation time is designed for the worker-machine idle time window to improve the local optimization performance of the algorithm; In addition, The improved crossover and mutation operators is designed to expand the global search range of the algorithm. Finally, through simulation experiments, the results of various algorithms are compared to verify the effectiveness of the proposed algorithm for isomorphism and isomerism factories instances.

Abstract： What is intelligence? is one of the core key questions of artificial intelligence, but there is no universally accepted definition. Based on the relationship between intelligence and life, this paper proposes that intelligence is the basic ability and characteristic attribute of living organisms, and it is the ability to achieve the maximum amount of information with the minimum energy as much as possible, and adapt to the environment and maintain existence through information processing. On this basis, this paper puts forward a new view that intelligence is the ability to convert material energy and information, further puts forward new concepts such as the measurement calculation method of intelligence, average intelligence, and comprehensive intelligence, and finally discusses the quantitative conversion relationship between matter, energy and information, points out the upper bound of intelligence and the lower bound of energy conversion into information, and further gives a dimensionless calculation formula for intelligence measurement in order to facilitate practical application. A feasible calculation method is given for the quantitative analysis of the intelligence of the intelligent system..
