WebProblem Statement. In mathematics, Gaussian elimination, also known as row reduction, is an algorithm for solving systems of linear equations. It consists of a sequence of … WebIn 1974, Tarjan proposed an algorithm that uses depth-first search and union-find to achieve an asymp-totic complexity of O(N logN+E)[29].Fiveyears later, Lengauer and Tarjan built on this work to produce an algorithm with almost linear complexity [22]. Both algorithms rely on the observation that a node’s

They are useful for designing reliable networks. For a disconnected undirected graph, an articulation point is a vertex removal which increases the number of connected components.
