  character strings
    s:This paper put forward a kind of improved genetic algorithm which combines the complex shape method with genetic algorithm and retains the good points of the original algorithm but overcomes some of their weak points suck as the operation of binary character strings, slow convergence speed and low probability for attaining the overall situational optimal solution etc.
    本文提出了一种将复合形法与遗传算法相结合的改进遗传算法,保留了原算法的优点,而克服了它们的一些弱点,如二进制字符串操作、收敛速度慢、获全局最优解的概率低等。

  string
Our basic tool is Lusztig's canonical basis and the string parametrization of this basis.
      
Based on the phase string theory, the t-J model reduces to a MCS theory for spinons and holons.
      
Boundary control of string vibrations that minimizes the integral of power p ? 1 of the module of control or its derivative
      
In this paper, boundary control of the third boundary condition at one end of a string, assuming that the other end is fixed, is studied.
      
Integral minimization of the second derivative module of the boundary control of string vibrations with the fixed end

  character string
Precise locating of character string is realized by exploiting horizontal projection and character arragements of binary images in horizontal and vertical directions respectively.
      
The hashing function is defined in terms of a trie, which is basically a binary tree where a character string is associated implicitly with each node.
      
Based on this cut-off criterion, a fast algorithm has been developed to find the nearest neighbors of a given character string in a dictionary.
      
It is demonstrated here that by introduction of three new operators, namely,position, fraction, andconcatenation, expressions of typical programming languages can be executed with a unified method starting from the character string.
      
Using a semiring interpretation, the weight of a morphological analysis result represents the possible linguistic interpretations of an input word, while the resulting character string itself represents the lemma of the input.

  character strings
Objects in a program are represented (denoted) as character strings that follow the grammatical rules given in the definitions of types.
      
And this system can easily generate relational data between facilities and character strings on maps.
      
Properties of the "error distance matrix" between two character strings are studied under the assumptions of the new model.
      
A cut-off criterion has been discovered, which can detect whether the error distance between two character strings is greater than a prespecified value during the calculation.
      
Time-varying key feature vectors of 264 synthesized sounds are extracted from an auditory-based pitch model and converted into character strings using PCA-analysis and classification trees.

s:This paper put forward a kind of improved genetic algorithm which combines the complex shape method with genetic algorithm and retains the good points of the original algorithm but overcomes some of their weak points suck as the operation of binary character strings, slow convergence speed and low probability for attaining the overall situational optimal solution etc.By means of the application on the domain of machine design, it has been proved that the new algorithm has got good applicational prospects in machine design.

本文提出了一种将复合形法与遗传算法相结合的改进遗传算法,保留了原算法的优点,而克服了它们的一些弱点,如二进制字符串操作、收敛速度慢、获全局最优解的概率低等。通过在机械设计领域中的应用,证明新算法在机械设计中有良好的应用前景

Two representation methods of parallel mechanisms, such as the matrix and character string representation, are presented in this paper. These representation methods are benefit for the automatic conceptual design of parallel robots.

对并联机构的结构描述问题进行了探讨,给出了描述并联机构结构的矩阵方法和字符串的方法,为空间机构特别是并联机构的数字化设计创造了条件。
