 * [http://www.mathpuzzle.com/MAA/54-Golf%20Tournaments/mathgames_08_14_07.html Mathpuzzle.com] has a few non-Dutch solutions for the "Social Golfer Problem".
 * [http://web.archive.org/web/20050407074608/http://www.icparc.ic.ac.uk/~wh/golf/solutions.html Warwick Harvey (web.archive.org)] had also published many solutions for groups with 10 or fewer groups and players of sizes in a simple to understand manner.
