An attempt (1) to determine whether a theory of creative thinking distinct from a theory of problem solving is needed, (2) to summarize what has been learned about problem solving by simulating certain human-problem-solving processes with digital computers, and (3) to indicate some of the differences in degree that may be observed in comparing relatively creative with relatively routine problem solving.
