The program runs under PDPROLOG ver.1.9, which is already available in PROLOG19.ARC. More information on ALGEBRA.ARC is listed below. With best regards, Sergio Vaghi SVAGHI@ESTEC.BITNET ....................................................................... COMPUTER ALGEBRA IN PROLOG -------------------------- Copyright 1987 S.Vaghi COMPUTER ALGEBRA IN PROLOG consists of four files: (READ.ME) is the present file. ALGEBRA.TXT is a short paper on computer algebra in Prolog. The paper is self-contained and includes the listings of the sample programs discussed, with several examples of applications. You can print it out on your Epson-compatible printer (it is formatted by a word processor, so if you browse through it on the screen you will see some "funny" characters appear). DIFFSV.PRO is a program in Prolog for the symbolic differentiation of algebraic functions. SIMPSV.PRO is a program in Prolog for the symbolic simplification of algebraic functions. The two programs are described in the paper, which should be read before using them. The programs run under PD Prolog (ver.1.9), a public domain Prolog developed by Bob Morein of Automata Design Associates, 1570 Arran Way, Dresher, PA 19025, who may be contacted to obtain a copy of the program. The programs should also run with little or no modification under other Prolog interpreters or compilers following the Edimburgh syntax. COMPUTER ALGEBRA IN PROLOG is placed in the public distribution, but the author retains the copyright of the paper and programs. You may copy and distribute COMPUTER ALGEBRA IN PROLOG provided that it is done free of charge, that all four files are copied without modifications and, in particular, the copyright notices are not removed or changed. I hope you will enjoy these programs. You can send comments and suggestions to S. Vaghi, ESTEC, P.O.
