always wonder where is part II.
- jart 4y agoI'm sure one of his other AI Memos could be considered that. For example: https://dspace.mit.edu/handle/1721.1/6099 https://dspace.mit.edu/handle/1721.1/6099
- Jtsummers 4y agoPer his homepage it “never appeared”. Which would mean never finished, I guess. > Part II, which never appeared, was to have had some Lisp programs for algebraic computation.
- adrian_b 4y agoThis text, with minor, mostly typographical, differences had been previously published internally as "MIT AI Lab. AI Memo No. 8" in March 1959. Two other earlier publications by McCarthy include various very important innovations, e.g. the conditional expressions in "AI Memo No. 1" (September 1958) and the "select" expressions (i.e. what are now named as "case" or "switch") in "AI Memo No. 4" (October 1958). The text published in CACM in 1960 is the conclusion of the memos written by McCarthy between 1958-09 and 1959-03, when most of the ideas on which LISP is based have been conceived. The "cond" and "select" expressions and the McCarthy "and" and McCarthy "or" expressions (i.e. C language && and ||) were not only new at that time, but they were much more convenient than the means used for expressing conditional execution in most later programming languages, which had various weird restrictions or peculiar syntax, for no good reason.
