Prolog

since 1972 (earliest usage recorded on this site was 1980)

Prolog is a general purpose logic programming language associated with artificial intelligence and computational linguistics.

Prolog has its roots in formal logic, and unlike many other programming languages, Prolog is declarative: The program logic is expressed in terms of relations, represented as facts and rules. A computation is initiated by running a query over these relations.

1980–1983

I learned Prolog from Dr. Kowalski, the guy who's work is the basis of prolog.

Like a few people (I'm looking at you Glen http://mytechne.com/user/growe/) I've had a few attempts to learn Prolog. First up was on a DEC-10, it had been installed and If I remember correctly I had to get special permission to use it. I've never got to grips with it though.

jtauber

1985–

Initially learnt (or attempted to learn) from the Turbo Prolog manual without having a copy of the software itself. I was 11 or 12, wanted to build artificial intelligence software and Fifth Generation languages were all the rage.

1986–1987

Bought C&M's book after working on a BYTE mag tutorial which had bugs.. so I fixed them and got the code running. Liked Prolog for logic IO sucked. I was hanging around with a work friend who was trying to bring it in, didn't get to code in it with the IDE - management was too cheap! Had to be Chim-chim in the trunk of the MACH5.

The class of the class class is the class class. My extremely brief intro to Prolog was in a seminar, so I'm not sure that even qualifies as a class.

[See Lisp.] Have made a few valiant attempts at learning Prolog, but I'm not recursive at heart I'm afraid. I just don't get it.

Yet another language used solely for comp.sci. degree.

I used it at the university for a course. Fun, but I would never use it to do something real.

collypops

Used very briefly in high school, in their super-advanced AI course. Hehe

Had to study it for a University exam. I thought it was very cool, as concept.

GordyBrow

Some really basic AI programming in high school. It would be interesting to have a closer look now.

Maybe if I had had a good professor in university I would have got it…

jonemo

2002–2010

Our high school teacher tried teaching a beginners CS class Prolog. He failed. I remember being able to solve all the assignments but still having no clue about what this language does. When Prolog came up in my grad school AI class, I was forced to look at it again and finally grasped many of the underlying concepts.

Used it for two courses, have been unable to really get to grips with it. I understand how it works easily enough, but it does not feel natural (unlike imperative and functional languages, which generally do to some extent). For this reason, I think it was very much worth learning. Most foreign language I've ever touched.
