SHRDLU

SHRDLU was one of the first computer programs to combine language understanding and the simulation of planned activities. It was developed in 1972 by Terry Winograd and allowed the manipulation of simulated building blocks in an imaginary environment via instructions in natural language.

Today there is no longer an executable version of SHRDLU. The original was written in Micro Planner and Maclisp (a variant of the Lisp programming language ), for which an interpreter no longer exists today. On the pages of Terry Winograd there is a reference to a new version programmed in Common Lisp . However, this does not have the same scope of functions as the actual SHRDLU.

The name is based on the order of the keys on a Linotype typewriter.
