Eachsections()call returns a structure containing nodes of a unique class created in a class factory function, where the unique class definition contains no logic except that it inherits from the Section class. This allows properties/methods added to one structure’s class definition to not affect...
The definition of the prefix Pi(x), and consequently of their (τ/2)-majorities Ci(x), however, is slightly modified: Pi′(x) is the sequence of the labels of the first 1+2i/τ nodes in the path from x to the root of its small subtree Fj, that is,Pi′(x)=〈label(x),...
