The Euler tour technique (ETT), named after Leonhard Euler, is a method in graph theory for representing trees. The tree is viewed as a directed graph that contains two directed edges for each edge in the tree. The tree can then be represented as a Eulerian circuit of the directed graph, known as the Euler tour representation (ETR) of the tree
The level ancestor query LA(v,d) requests the ancestor of node v at depth d, where the depth of a node v in a tree is the number of edges on the shortest path from the root of the tree to node v. It is possible to solve this problem in constant time per query, after a preprocessing algorithm that takes O( n ) and that builds a data structure ...
An Eulerian trail, [note 1] or Euler walk, in an undirected graph is a walk that uses each edge exactly once. If such a walk exists, the graph is called traversable or semi-eulerian. [3] An Eulerian cycle, [note 1] also called an Eulerian circuit or Euler tour, in an undirected graph is a cycle that uses each edge exactly once
He was the grandson of Bertrand-François Mahé de La Bourdonnais. He learned chess in 1814 and began to take the game seriously in 1818, regularly playing at the Café de la Régence . [ 1 ] He took lessons from Jacques François Mouret , his first teacher, [ 2 ] and within two years he became one of the best players of the Café .

De La Bourdonnais was considered the world's leading player from 1821, when he surpassed his mentor Alexandre Deschapelles. In 1823 La Bourdonnais defeated William Lewis, Britain's leading player, in a match in London, and in the spring of 1825 he played and defeated the best players that England had to offer. Nine years later he returned to ...
