- I just uploaded my simplex library v1.1 (the first public release) to
- seq.uncwil.edu in the hp48/Uploads directory.

- Well I finally did it. I rewrote Ricardo Marimon's simplex procedure
- entirely in sysRPL and made it into a library. It now stores all temporary
- variables as a Library Data object in a variable called LPdat in
- the current directory. This makes the program a little more idiot proof
- since you cannot alter the problem directly.
-
- The library itself bytes out (on the HP) at 15800.5 with a checksum of # D7DCh
- and uses lid # 517h (1303d). I created the .asc file with tasc
- on my sun and have not tested if it extracts properly.
-
- Currently it only implements the 2 phase method to find an initial
- feasible solution, but a primal-dual method is on the drawing board.
-
- The user accessible functions do quite a bit of error checking, but I
- cannot guarantee that this library will not cause memory loss.
- I will graciously accept any and all bug reports and suggestions.
- Also, I will maintain a list of 'registered users' to whom
- I'll automatically send updated libraries. Just send me a note
- including your email address.
-
- I do graciously thank Ricardo for doing all the hard work on the
- matrix manipulation and the original logic of the program. Also
- the .doc file is almost entirely verbatim from his original posting.
