[net.ai] AI in IAsfm

grady@ingres.Berkeley.EDU.BERKELEY.EDU (Steven Grady) (05/15/86)

In the June 86 issue of IAsfm ,there's a fascinating article on AI and
common sense.  In this article, the author mentions a program called
Eurisko, which I had heard about before briefly, but which I'm now
reminded of.  Do people have references to this?  How can I find out
more about it?

Douglas Lenat has written and exercised two heuristic "discovery" programs,
AM and EURISKO.
His initial exploration of the problem of heuristic (mechanical)
discovery constituted his Ph.D. research and culminated in the somewhat
controversial program, AM.
After his thesis, Lenat analyzed the shortcomings and strengths
(or "sources of power" as he came to call them) of AM, and from
this analysis EURISKO was conceived.
Unfortunatley, since Lenat's move from Stanford to MCC (Austin) a year
or two ago, he has ceased working with EURISKO.

I am aware of one or two isolated, low-profile projects to build
EURISKO-like systems. Most notable is the work of Ken Haase at MIT
on a system called CYRANO -- but I don't think any of Haase's work
has yet been published.
