o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o~~~~~~~~~o My name is Jon Awbrey. I have returned to university in my 50's to work on a doctorate in systems engineering and also to "capstone" a few old projects that I did not get to finish up in my last millennium. In the process I have dug up one of my old unfinished programming symphonies that I thought I might offer to the Haskell community as a potentially interesting exercise or project, since one of the things that I was trying to do there was to transpose Pascal into a functional style. The main idea of the program is to integrate an "empiricist" learning algorithm (working on 2-level formal languages) with a "rationalist" reasoning algorithm (working at the level of propositional calculus). It implements (what I used to think of as) some pretty radical graph-theoretic data structures, extending some ideas of C.S. Peirce on graphical syntaxes for propositional logic. (I had started this somewhat before Conceptual Graphs hit the streets.)
I have begun documenting this work in a detailed way at the following list site, dedicated to this and related purposes: http://stderr.org/pipermail/inquiry/ http://stderr.org/cgi-bin/mailman/listinfo/inquiry You can also get the postings in newsgroup format from Gmane: http://gmane.org/ http://news.gmane.org/ http://news.gmane.org/thread.php?group=gmane.comp.inquiry The Pascal source code is here: 01. http://stderr.org/pipermail/inquiry/2003-March/000115.html 02. http://stderr.org/pipermail/inquiry/2003-March/000116.html 03. http://stderr.org/pipermail/inquiry/2003-March/000117.html 04. http://stderr.org/pipermail/inquiry/2003-March/000118.html 05. http://stderr.org/pipermail/inquiry/2003-March/000119.html And I will send the Exe file to anybody who wants it.
