Kamynin, S. S.; Lyubimskii, E. Z. – 1969
The document describes the ALMO programing language. (Author)

Radhakrishnan, T.; Venkatesh, K. – Journal of the American Society for Information Science, 1978
An earlier model which proposed to determine the optimum number of shelves to minimize shelving cost of a book collection does not always yield optimal value. Underlying assumptions from this earlier model, which aren't always practical, are discussed, and algorithms providing a better solution for the same problem are presented. (Author)

Horabin, Ivan S.; Lewis, Brian N. – Improving Human Performance Quarterly, 1977
Historical review of the development and dissemination of ordinary-language algorithms. (STS)
Descriptors: Algorithms, Educational Development, History, Instruction
Tiemann, Philip W. – Improving Human Performance Quarterly, 1977
Early analysis sought to identify tasks while recent techniques focus upon analysis of the content of tasks and are more prescriptive. Examples of such analysis appropriate to sequential tasks, one behavior chain task and one algorithm task, are presented to illustrate the prescriptive function of content analysis. (Author)

Goyal, Pankaj – Journal of the American Society for Information Science, 1984
Investigates techniques for automatic coding of English language strings which involve titles drawn from bibliographic files, but do not require prior knowledge of source. Coding methods (basic, maximum entropy principle), results of test using 6,260 titles from British National Bibliography, and variations in code element ordering are…

Lowe, Thomas – Journal of the American Society for Information Science, 1971
Frequently it is useful to abbreviate or otherwise transform keys used for information retrieval. Given a transformation algorithm and data to be transformed, certain qualities of the algorithm relating to retrieval problems can be characterized. This paper gives some measures of effectiveness of such transformation algorithms. (11 references)…

Phillips, J. P. N. – Psychometrika, 1982
An algorithm, using a short cut due to Feldman and Klingler, for the Fisher-Yates exact test is presented. The algorithm is quick, simple and accurate. (Author)

Finkbeiner, C. T.; Tucker, L. R. – Psychometrika, 1982
The residual variance is often used as an approximation to the uniqueness in factor analysis. An upper bound approximation to the residual variance is presented for the case when the correlation matrix is singular. (Author/JKS)

Dolker, Michael; And Others – Psychometrika, 1982
Efron's Monte Carlo bootstrap algorithm is shown to cause degeneracies in Pearson's r for sufficiently small samples. Two ways of preventing this problem when programing the bootstrap of r are considered. (Author)

Craven, Timothy C. – Journal of the American Society for Information Science, 1982
Describes a system for the automatic coding of most descriptive titles which generates Nested Phrase Indexing System (NEPHIS) input strings of sufficient quality for permuted index production. A series of examples and an 11-item reference list accompany the text. (JL)
Descriptors: Algorithms, Automatic Indexing, Permuted Indexes

Hafner, Robert – Psychometrika, 1981
The method proposed by Harman and Fukuda to treat the so-called Heywood case in the minres method in factor analysis (i.e., the case where the resulting communalities are greater than one) involves the frequent solution of eigenvalue problems. A simple method to treat this problem is presented. (Author/JKS)

ten Berge, Jos M. F.; And Others – Psychometrika, 1981
Several algorithms for computing the greatest lower bound to reliability or the constrained minimum-trace communality solution in factor analysis have been developed. The convergence properties of these methods are examined. A uniqueness proof for the desired solution is offered. (Author/JKS)

Price, Lewis C. – Psychometrika, 1980
Two algorithms based on a latent class model are presented for discovering hierarchical relations that exist among a set of dichotomous items. The algorithms presented, and three competing deterministic algorithms are compared using computer-generated data. (Author/JKS)
