Implementing “Hidden” Strategies
Giulio Zambon · Apress eBooks · 2015
The two “hidden” strategies, hidden pair and hidden triple, have the same general design: first, they build lists of the cells containing each candidate number; then, they analyze the lists to see whether pairs or triples are hidden inside the lists. These keywords were added by machine and not by the authors. This process is experimental and the keywords may be updated as the learning algorithm improves.
