Accelerating Cryptanalysis with the Method of Four Russians.

WebThis algorithm is widely known as the Four Russian Algorithm and it improves the running time by a factor of O (log n) (with a run time of O (n2 / log n)) to compute just the value of the edit distance. It does not address the problem of computing the actual edit script, which is of wider interest rather than just the value. Algorithms to which the Method of Four Russians may be applied include: computing the transitive closure of a graph,Boolean matrix multiplication,edit distance calculation,sequence alignment,index calculation for binary jumbled pattern matching. In each of these cases it speeds up the algorithm by … See more In computer science, the Method of Four Russians is a technique for speeding up algorithms involving Boolean matrices, or more generally algorithms involving matrices in which each cell may take on only a bounded … See more The main idea of the method is to partition the matrix into small square blocks of size t × t for some parameter t, and to use a lookup table to … See more The algorithm was introduced by V. L. Arlazarov, E. A. Dinic, M. A. Kronrod, and I. A. Faradžev in 1970. The origin of the name is unknown; Aho, Hopcroft & Ullman (1974) explain: See more maningrida community store
