An algorithm is presented which makes it possible to sort character strings containing German umlauts by German sort rules within an appropriate execution time. For that purpose a modified ordinal function is designed yielding an ordinal number of every ASCII-character. This supplies the stepwise decisions for a correct sorting of diacritical character strings. The demonstrated solution can be adapted to other character sets and standards simply by using other values in the ordinal number table.

With the success of CAD firmly established, documentation is the next logical target for productivity gains through automation. Significant productivity improvements result when a documentation system is used to manage the hundreds of changes and revisions which are part of every written project. One application area where the need for document change control is especially needed is computer-Aided Software Engineering (CASE). Demands for faster software development set the stage for early programs which interpreted flowcharts to produce a program design language (PDL) document. Most first-generation CASE vendors have discovered that structured programming tools alone do not provide a complete solution to managing software development. There is an equally important need for documentation that can be generated in conjunction with the program itself. Newer CASE tools strongly emphasize documentation as an integral part of the software development process and the use of automated tools to expedite this process.

Several factors influence the performance of a table construction and lookup system. The most important is the number of comparisons needed to locate the required position in the table. Less important, but still significant, is the complexity and number of other calculations required, and the amount of data rearrangement needed. A lookup table access method that combines simplicity, good overall performance, and sorted data is presented.

There is a growing need in the field of molecular biology for multiple sequence alignment programs that infer homology based on sequence similarity. Seven multiple sequence alignment programs have been obtained from the respective authors and are presently available to members of the BIONET community.

Utility programs bridge the gaps between application programs. In this article, the author looks at a few utility programs that are truly productivity-oriented, conceived to save time and make your computer a more efficient tool. And the best news of all: they all retail for less than one hundred dollars. One such inexpensive utility program, known as Cubit, can provide more hard disk storage space by compressing the files on the disks and later re-expanding them when needed. Another example is a text retrieval software called ZyIndex, which specializes in ferreting out misplaced information on file-choked hard disks. Still another such program is Tornado, a memory-resident utility which provides a pop-up, indexed note pad that can be summoned during any program. It's ideal for jotting down phone messages, reminders or unexpected brainstorms.

The development of the theory of GMDH sorting methods in the last five years is examined. GMDH theory is presented as a continuous process of interpretation of the empirical results of sorting of models or clusterings obtained on a computer. Both the computational experiments and their theoretical interpretation must be concentrated in the hands of a single investigator or a single team of investigators. The lack of unity of practice and theory slows down the advance of GMDH and causes the appearance of papers that are vulnerable to criticism (from an experimental or theoretical standpoint).

Differential consistency and balance of variables criteria are the best for sorting (or self-organization) of models when the data sample is small. Special procedures for regularization and for attaining the unimodality of the criterion characteristic are described. These equations are subject to sorting in order to obtain the optimal model. Then, an iterational convergent multiseries linear (CML) algorithm ensures the obtaining of an optimal model in the form of a system of systems of equations. The computer time is estimated for successive application of the OSA and CML algorithms.

A sequence of real numbers is called twisted if it can be produced from the sorted sequence by repeatedly reversing the order of consecutive subsequences. It is shown that twisted sequences constitute a class of exponentially many members each of which can be recognized and sorted, by a simple on-line algorithm, in linear time.

Characteristics of user-developed software applications and their documentation requirements are reviewed, and the results of a study undertaken to identify factors affecting the level of documentation required by these applications are reported. The results provide a framework to guide computer-using management in formulating standards for a broad spectrum of such applications.
