There exits several MDO algorithms. But they are in our opinion either nonefficient or complicated. So we devised an algorithm called Subspace Approximation Optimization . In the SAO algorithm, the whole system is decomposed into one system-level optimization and several disciplinary optimizations so that a large and complicated problem can be divided into several easy-solving sub-problems. The coupling relationships and the coordination among disciplines are presented by equality constraints and these equality constraints are assigned to relevant disciplines. The optimums of design variables in system level optimization are transferred to discipline level optimization. The optimums of design variables in discipline level correspond to the point that is the nearest to the optimums of design variables in system level. If the optimums of design variables in system level are out of feasible region of discipline 1eve1, linear constraints can be built in the system level optimization using the design variable optimums obtained by the discipline level optimization. The system level optimization would improve the design of the whole system with these linear constraints.
目前,国内外已经发展出了多种飞机多学科设计优化算法,本文的重点是针对协同优化算法的不足,提出了子空间近似优化算法(Subspace ApproximatingOptimization,SAO),SAO算法中,整个系统的优化问题被分解成一个系统级优化和若干学科级优化,而各个学科之间的耦合与权衡关系则被当作等式约束,这些等式约束将被分配到各个学科级优化中去,系统级优化的任务是寻找整个系统的最优解,而学科级优化的目标函数是以系统级优化分配下来的设计点为圆心的超球半径的平方,因此,如果系统级优化分配下来的设计点在学科级优化可行域内,则学科级优化目标函数为0,反之,则学科级优化的最优点是系统级优化当前设计点距离可行域最近的点。

A fine-grained genetic algorithm based algorithm which is for the parameters optimization problem of agent model is proposed. The fine-grained genetic algorithm is used to solve the parameters optimization problem of agent model. As to the parameters optimization problem of the agents colony model, the first step is to define the concept of "the parameters mode of the combat agents colony" to describe the parameters of the combat agent colony model. Then the genetic algorithm is used to solve the optimization problem with the parameters mode of the combat agent colony model as the genetic individual.

The means to solve this problem is to translate it into a kind of antagonism problem, then use the competitive co-evolutionary genetic algorithms to solve it.

PSO is a population-based optimization algorithm, which mimics the social behavior of animals in a flock. It makes use of individual and group memory to update each particle position allowing global and local search optimization.
