The parenthesis theorem and the white path theorem involve parent nodes and descendants found using this algorithm, which can also display the Nested Interval Property as a result of its recursive nature.

The parenthesis theorem and the white path theorem involve parent nodes and descendants found using this algorithm, which can also display the Nested Interval Property as a result of its recursive nature. Applied to a situation in which an optimal quantity is sought, it becomes known as "Best-First," and it can also be used to determine if a graph has an Euler tour by detecting cycles in the graph. It considers outgoing edges of a vertex before any neighbors of that vertex. FTP, name this search algorithm, which explores as far down a graph as possible before backtracking, unlike its logical counterpart, breadth-first search.
