Controlled-bias generator and collection
I've made public on GitHub my collection of 5,926,343 puzzles generated with the controlled-bias generator: https://github.com/denis-berthier/Controlled-bias_Sudoku_generator_and_collection.
It also contains the (main versions of the) generators used to create it (they were already public before, on this forum and on my website).
It also contains updated versions of my webpages related to Comparisons of (bottom-up, top-down and controlled-bias) generators and to Classification results (the W classification) obtained with CSP-Rules/SudoRules.
