Halley's method is an iterative numerical technique used to find roots of real-valued functions. It is named after the astronomer Edmond Halley and is a generalization of Newton's method, which is also used for root-finding. Halley's method is particularly useful for finding roots when the function has multiple derivatives available, as it incorporates information from the first two derivatives.
