- In means-ends analysis: History
…scientists called their model the General Problem Solver (GPS). GPS would recursively apply heuristic techniques in solving a given problem and conduct a means-ends assessment after each subproblem was solved to determine whether it was closer to the intended solution. Through this process, GPS could find solutions to mathematical theorems,…

Called the General Problem Solver, it could find solutions to a wide range of fairly structured problems, such as logical proofs and mathematical word problems. This research, based on a heuristic procedure called “means-ends analysis,” led Newell and Simon to propose a general theory of problem solving…

work of Newell
- In Allen Newell
Their next project was the General Problem Solver (GPS), which first ran in 1957. Given a problem, GPS would repeatedly apply heuristic techniques (modifiable “rules of thumb”) and then perform a “means-ends” analysis after each step to verify whether it was closer to the desired solution.
