Article Summary:
This article discusses the optimization of the ApplicativeDo algorithm in the Glasgow Haskell Compiler (GHC), which is used to improve the performance of Haskell programs. The author presents a new approach to solving the O(n³) complexity problem, inspired by computational biology, and shows that it can reduce the compile-time complexity to Õ(n^2.8244).
