首先，历史背景导致的最优准则的方法进行了讨论，指出传统的设计方法的作用，一方面，普拉格的工作的基础上变分原理的另一方面，作为两个激励的影响。其次是利用离散化结构或模型的可分性属性的方法的正式发展。的重要性，单约束的情况下指出，并提出了相关的特别简单而强大的最优性准则，然后扩展到多个约束。通过算例说明了位移、应力和特征值相关约束的求解方法。
First, the historical background leading to the optimality criteria approach is discussed pointing out the role of the traditional design methods on one hand, and Prager’s work based on variational principles on the other hand as the two motivating influences. This is followed by the formal development of the method utilizing the separability properties of discretized structures or models. The importance of the single constraint case is pointed out and the associated particularly simple yet powerful optimality criteria is presented followed by extension to multiple constraints. Examples are used to illustrate the approach for displacement, stress and eigenvalue related constraints.
