A Simulation in C++ of Joseph Weizenbaum’s 1966 ELIZA
I’ve made in C++ what I think is an accurate simulation of the original ELIZA. It is a console application that takes as input the original format script file, which looks like a series of S-expressions, and then waits for the user to type a line of text before responding with a line of text of its own.
I made this before the ELIZA source code had been found, and wrote about it in part 1.
Part 2 describes changes I made after the ELIZA source code was found.
Part 3 is about the HASH function, now that too has been found.
In a footnote I document trying to recreate the PARRY/DOCTOR conversation from RFC439.
My son Max Hay and I recreated ELIZA in JavaScript here. Try it here.
