NettetKernighan's original 1978 implementation of Hello, World! was sold at The Algorithm Auction, the world's first auction of computer algorithms. [21] In 1996, Kernighan taught CS50 which is the Harvard University introductory course in Computer Science. Nettet27. des. 2024 · Implementations of the Lin-Kernighan heuristic such as Keld Helsgaun's LKH may use "walk" sequences of 2-Opt, 3-Opt, 4-Opt, 5-Opt, “kicks” to escape local minima, sensitivity analysis to direct and restrict the search, as well as other methods. LKH has 2 versions; the original and LKH-2 released later.
