A STATE-SPACE TECHNIQUE FOR OPTIMAL-DESIGN OF MECHANISMS
收藏 引用
JOURNAL OF MECHANICAL DESIGN-TRANSACTIONS OF THE ASME 1982年 第4期104卷 792-798页
作者: SOHONI, VN HAUG, EJ V. N. Sohoni E. J. Haug Division of Materials Engineering College of Engineering The University of Iowa Iowa City Iowa 52242
Problems of optimal design of mechanisms are formulated in a state space setting that allows treatment of general design objectives and constraints. A constrained multi-element technique is employed for velocity, acce... 详细信息

AUXILIARY PROBLEM PRINCIPLE AND DECOMPOSITION OF optimization PROBLEMS
收藏 引用
JOURNAL OF optimization THEORY AND APPLICATIONS 1980年 第3期32卷 277-305页
作者: COHEN, G INST RECH INFORMAT & AUTOMAT LAB F-78150 LE CHESNAY FRANCE
The auxiliary problem principle allows one to find the solution of a problem (minimization problem, saddle-point problem, etc.) by solving a sequence of auxiliary problems. There is a wide range of possible choices fo... 详细信息

COMPUTER-SYSTEM DESIGN USING A HIERARCHICAL APPROACH TO PERFORMANCE EVALUATION
收藏 引用
COMMUNICATIONS OF THE ACM 1980年 第9期23卷 511-521页
作者: KUMAR, B DAVIDSON, ES UNIV ILLINOIS COORDINATED SCI LABURBANAIL 61801
The concept of a hierarchy of performance models is introduced. It is argued that such a hierarchy should consist of models spanning a wide range of accuracy and cost in order to be a cost-effective tool in the design... 详细信息

BENCH MARK EXPERIMENT FOR MINIMIZATION algorithms
收藏 引用
MATHEMATICS OF COMPUTATION 1979年 第145期33卷 249-264页
作者: LYNESS, JN Applied Mathematics Division Argonne National Laboratory Argonne IL 60439 United States
Abstract: In this paper we suggest a single bench mark problem family for use in evaluating unconstrained minimization algorithms or routines. In essence, this problem consists of measuring, for each algorithm... 详细信息

AFFINE SCALE-INVARIANCE OF MINIMIZATION algorithms
收藏 引用
MATHEMATICS OF COMPUTATION 1979年 第145期33卷 265-287页
作者: LYNESS, JN Applied Mathematics Division Argonne National Laboratory Argonne IL 60439 United States
Abstract: Let $f(x)$ be a general objective function and let $\bar f(x) = h + mf(Ax + d)$. An analytic estimation of the minimum of one would resemble an analytic estimation of the other in all nontrivial resp... 详细信息
