Without a conceptual framework to encapsulate details, algorithm designers are often forced to resort to proof by cases or ‘manyscenarios’ reasoning to show correctness and impossibility results. As Yemini and Cohen put it, “proving protocols correct (or impossible) is a difficult and cumbersome art in the absence of pr...
