Before revision: In the field of artificial intelligence, the most difficult problems are informally known as AI-complete or AI-hard , implying that the difficulty of these computational problems, assuming intelligence is computational, is equivalent to that of solving the central artificial intelligence problem—making computers as intelligent as people .Shapiro, Stuart C. (1992).
After revision: In the field of artificial intelligence, tasks that are hypothesised to require artificial general intelligence to solve are informally known as AI-complete or AI-hard .Shapiro, Stuart C. (1992).
