In symbolic computation (or computer algebra), at the intersection of mathematics and computer science, the Risch algorithm is an algorithm for indefinite integration. It is used in some computer algebra systems to find antiderivatives. It is named after the American mathematician Robert Henry Risch, a specialist in computer algebra who developed it in 1968. Using only the above description and what you know about the world, "The Risch algorithm system developed in the 1960's is used exclusively to find antiderivatives." is definitely correct, incorrect, or inconclusive?
