Four algorithms for subtraction are described: borrow and pay back,'' equal additiions, shopkeepers' subtraction,'' and decomposition. (DT)

An algorithm, based upon factor analytic theory, is presented to illustrate one solution to the problem of selecting items for a test. (Authors)

Virtual scatter storage schemes are well suited dictionaries, having both rapid lookup and economy of storage. (MF)

Minimum trace factor analysis has been used to find the greatest lower bound to reliability. This technique, however, fails to be scale free. A solution to the scale problem is proposed through the maximization of the greatest lower bound as the function of weights. (Author/JKS)

Discusses the various problems encountered when scheduling examination timetables and a means for overcoming them using a computer-based examination management system to provide the registrar with an analysis and feedback to eliminate conflicts. The system uses color-coding to produce blocks of nonconflicting examinations. (EAO)

This approach to task analysis includes descriptions of (1) inputs, outputs, and jobs; (2) flow of materials and decisions between jobs; (3) inputs, major tasks, and outputs of each job; (4) sequence of steps for major tasks; (5) heuristics/algorithms for each sequence step; and (6) information needed to use heuristics algorithms. (EAO)

A previously developed program for the HP-41C programmable calculator is extended to handle models of differential and difference equations with multiple eigenvalues. How to obtain difference equation solutions via the Z transform is described. (MNS)

A technique for doing long division without the usual estimation difficulty is presented. It uses multiples of 2 combined with a recording technique. (MNS)

Describes a computer-assisted scheduling algorithm for college courses and faculty. The method considers such issues as availability of lecturers, preferred times for courses, and time conflicts. Samples of the schedules are included. (JJD)

The repetitious nature of music is thought to be very similar to the repetitious nature of computer algorithms. Subroutines are seen to be very effectively applied to music notation, through reducing repetitious entry and the amount of memory required to represent a musical score. Examples of subroutine use are provided. (MP)

Addresses the problem of systematic biases which affect the way that individuals construct and modify search queries on online retrieval systems, and suggests a searching algorithm that helps to avoid the effect of those biases. (FM)
