A summary of the work done in the field of analytic differentiation by computer is presented. It is shown that there exists a need for an analytic differentiation routine whose output can be processed by a regular algebraic compiler. An algorithm is presented which will transform a FORTRAN FUNCTION subprogram into a FORTRAN SUBROUTINE subprogram that evaluates both the original function and its first derivative with respect to one independent variable. Implementation of this algorithm and possible extensions to it are discussed. / Science, Faculty of / Computer Science, Department of / Graduate

A covariance analysis procedure which compares multiple linear regression equations is developed by extending the general linear hypothesis model of full rank to encompass heterogeneous data. A FORTRAN IV computer program tests parallelism and coincidence amongst sets of regression equations. By a practical example both the theory and the computer program are demonstrated. / Graduate and Postdoctoral Studies / Graduate

Implementation of the Fletcher-Reeves optimization strategy into the GOSPEL optimization package is examined. An explanation of the GOSPEL package is provided, followed by the presentation of the Fletcher-Reeves strategy. Performance of all strategies in the updated GOSPEL package are compared for nine test cases. A user manual for GOSPEL operation as well as the source code are also included.

The Configuration Control and Management of Trainer Systems Software has been recognized as a significant problem for many years. Many software tools are being developed for use as aids in this task. The efforts of the Department of Defense in the development of Ada and an Ada Programming Support Environment (APSE) have strongly addressed the problems of configuration control and management. However, these efforts have been targeted for Ada-based software as it is anticipated it will be the primary language of the DOD. The author feels that FORTRAN based software will require maintenance for many years even after the acceptance of Ada, and that the features of the APSE could be applicable to this task. The Ada Language System (ALS), which will soon be available, is the Army's implementation of the Ada Programming Support Environment. ALS has also been accepted by the Navy. This paper discusses the applicability of the ALS to the problem of FORTRAN-based software configuration control and management. A basic demonstration tool will be developed and analyzed.
