The development of industry is in the project. Under the background of socialism with Chinese characteristics entering a new era, facing the development pattern of "double circulation" and focusing on the development goal of "double carbon", the construction of grass-roots projects is facing problems and dilemmas in terms of ideology, policies and measures, and promotion path. Based on the new development stage, implementing the new development concept, integrating into the new development pattern, strengthening the construction of grass-roots projects, and promoting the transformation and upgrading of the county economy, we need to broaden our vision, change our thinking, and strengthen measures in the fields of carrying out special research, breaking the constraints of factors, and using sufficient market means to effectively guarantee the steady and far-reaching development of the county economy and society.展开更多

This paper proposes a new Linkage Learning Genetic Algorithms, named m-LLGA. With the linkage learning module and the linkage-based genetic operation, m-LLGA is not only able to learn and record the linkage information among genes without any prior knowledge of the function being optimized. It also can use the linkage information stored in the linkage matrix to guide the selection of crossover point. The preliminary experiments on two kinds of bounded difficulty problems and a TSP problem validated the performance of m-LLGA. The m-LLGA learns the linkage of different building blocks parallel and therefore solves these problems effectively; it can also reasonably reduce the probability of building blocks being disrupted by crossover at the same time give attention to getting away from local minimum.展开更多
