An AI model from Open AI has solved a math problem formulated in 1946 by Paul Erdős. Svante Linusson, professor at KTH, expressed shock at the result.
The problem concerns how many equal-length lines can be drawn between points on a sheet of paper. Erdős's theory that the most lines are achieved in a grid proved incorrect.
The AI model used tools from another area of mathematics and wrote its own research article on the solution. Linusson assesses that the article could have been published in top journals if written by a human.
