The embodiment of the invention discloses a dislocation and fission algorithm for solving the technical problem of searching many blind spots in the existing intelligent optimization algorithm and easily falling into the local optimal impasse, which is easy to produce premature convergence and slow convergence and long execution time. The method comprises a step one of selecting the multidimensional optimal particle and the multidimensional sub-optimal particle from the population; a step two of carrying out dislocation or fission of one dimension value of the multidimensional optimal particle and the multidimensional sub-optimal particle, and enabling the multidimensional optimal particle and the multidimensional sub-optimal particle to mutually learn from each other or a locally optimal dimension of the multidimensional optimal particle and the multidimensional sub-optimal particle to separate; a step three of carrying out iteration and update of the multidimensional optimal particle and the multidimensional sub-optimal particle which are subjected to dislocation or fission in terms of one dimension value; and a step four of determining whether the multidimensional optimal particle and the multidimensional sub-optimal particle after iteration and update reach a preset termination condition or not, ending the algorithm if yes, otherwise, carrying out the step one.
Description
technical field [0001] The invention relates to the field of intelligent optimization algorithms, in particular to a dislocation fission algorithm. Background technique [0002] Optimization is an important research object in the fields of scientific research, engineering technology and economic management. For example, in engineering design, how to select parameters under certain constraints so that the design scheme can meet the requirements and reduce costs; in resource allocation, how to allocate limited resources so that the allocation scheme can meet the basic requirements of all aspects and Good economic benefits can be obtained; in various fields of human activities, and so on, there are too many to list. [0003] Optimization algorithm is an application technology based on mathematics for solving the optimal solutions of various engineering problems. It has been rapidly promoted and applied in engineering fields such as system control, artificial intelligence, pat...
