Abstract

The invention relates to an improved particle swarm-based offshore static target search scheme generation method. The method comprises the steps of establishing a calculation model of an offshore search task success rate; mapping the problem space to an algorithm space, and initializing a population; executing the first stage: performing iterative search in the solution space by utilizing the population through an iterative strategy, and analyzing the form of the solution space; executing a second stage: updating the population iteration strategy according to the solution spatial form, and performing iterative search to obtain a result after the iterative search is updated; and mapping the result after the update iteration search back to the problem space to obtain a search scheme and thetask success rate of the scheme. Historical data obtained by the population in the search process can be effectively utilized, the form of the solution space is analyzed, the search strategy is updated, and finally a high-quality search scheme is generated.

Description

technical field [0001] The invention relates to the field of target optimization, in particular to a method for generating sea stationary target search schemes based on improved particle swarms. Background technique [0002] The formulation of search plan for stationary targets at sea is one of the most basic research issues in the field of maritime search and rescue, and it has always been a difficult research point. The search plan formulation problem is essentially an optimization problem in mathematics. It is usually solved by using heuristic optimization method and iterative optimization using population.
