查询词典 problems

Although problems and limitations remain, management science has developed as an effective means for solving tedious but limited problems. Algorithms, or exact procedures for optimum solutions, have been developed for problems that are well defined or repetitious, and where a universal unidimensional cardinal scale utility, such as money, can reasonably be used as a measure of the desired outcome.

虽然一直存在着缺陷和问题，但是科学管理已经发展成为解决复杂问题的很好方法，种算法，或者是一种最优选择的方法，已经发展为解决问题的一种很好的界定或者反复的工作模式，是一种单一维度和协和效用尺度，例如金钱就可以经常用来衡量产出。

Finally the zeroth order optimization method is presented for two dimensional shape optimization problems.

本研究将从一般广为设计者所采用的一次最佳化方法--线性序列规划法的修正研究，以使其更稳定且更有效率地解决在一般结构与形态最佳化问题，包含有连续式及非连续式设计变数的最佳化问题演算过程，最后应用零次最佳化方法概念在二维形态最佳化设计上。

Many methods are used to solve nonlinear problems, their rate of convergence is quick, for example, Newton-moser method, King-werner method, they are attentioned widely because of the quick rate of convergence. While these methods are used to solve singular problems, the rate of convergence is slow, it is discommodious for us to solve practical problems.

有许多方法在求解非奇异问题时，它们的收敛率是很快的，有些甚至能达到二次收敛，例如Newton-Moser法、King-werner法，这是所熟知的，因其收敛速度快，并且简单易用而广受重(来源：AB17C论文dddd网www.abclunwen.com)视。
