The Chudnovsky algorithm is a fast method for calculating the digits of π (pi). Developed by the Chudnovsky brothers, it uses a series of mathematical formulas that converge rapidly, allowing for the computation of millions of digits of π efficiently. This algorithm is particularly useful in computer programming and numerical analysis. The Chudnovsky brothers, David and Gennady, are mathematicians known for their contributions to number theory and computational mathematics. Their work on the Chudnovsky algorithm has made significant impacts in the field, especially in the pursuit of calculating π to record-breaking lengths.
