Deletion of Induction puzzles

Comment: I do not feel that this is promotional in nature (although the nominator has explained their reasoning on that issue); however, as has been mentioned, it is one of the few in-depth explanations of the subject. Without reliable sources cited, this would seem to indicate that this is |Original Research. The main reason why it is getting hits at the moment is because of the passing mention in TechRadar's article - but this does not indicate that the subject meets the criteria for inclusion. A quick search did not yield indepth coverage of the subject anywhere that is reliable - and most of the "coverage" appears to be referring to puzzle books containing these kinds of puzzles, rather than a discussion about them. Although an interesting subject, that is not a criteria for inclusion... and this article (especially with no citations) does not meet the |criteria for inclusion
