Could someone send me information on the current status of Maple - what does it run on, what progress has been made in the past two years, what does it cost, etc.? thanks in advance! Steve Crandall ihnp4!mhuxt!evans

Some highlights of progress in the "past two years": - gcd (the heuristic "gcdheu" handles most problems with a few variables, and there is a complete package for univariate and multivariate Hensel lifting -- the EEZ method -- to handle the larger problems) - factor (complete multivariate package via Hensel (EEZ); univariate problems use a heuristic a la gcd above, when possible; otherwise, there is a Berlekamp/Hensel code for harder univariate problems) - ifactor (integer factorization via a 4-stage polyalgorithm that includes the Morrison-Brillhart method) - solve (for both linear and nonlinear problems, a technique based on substitutions has been quite successful -- much additional work has been done on solve for version 4.0, not yet released) - int (heuristic-based methods plus a partial implementation of the Risch integration algorithm) - tables and arrays (a very general table data structure, and a restriction of tables to traditional arrays -- all based on hashing techniques) - linalg (a package for linear algebra operations, including matrix arithmetic, determinants, eigenvalues, etc.) - garbage collection (facility introduced in version 3.3) - prettyprinting of multi-line expressions - help (an extensive on-line help facility) - Maple User's Guide (a comprehensive guide containing a 100-page tutorial and a 200-page reference manual) References ---------- B.W.
