WebApr 6, 2024 · 1 Answer Sorted by: 2 The algorithm, based on DFS, typically maintains a "visited" boolean variable for each vertex, which contains one bit of information - this vertex was already visited or not. So, none of vertices can be visited more than once. If the graph is connected, then starting the DFS from any vertex will give you an answer right away. WebBrent’s cycle detection algorithm is similar to floyd’s algorithm as it also uses two pointer technique. But there is some difference in their approaches. Here we make one pointer stationary till every iteration and teleport it to other pointer at every power of two.

Cycle detection has been used in many applications. • Determining the cycle length of a pseudorandom number generator is one measure of its strength. This is the application cited by Knuth in describing Floyd's method. Brent describes the results of testing a linear congruential generator in this fashion; its period turned out to be significantly smaller than advertised. For more complex generators, the sequence of values in which the cycl… WebMar 24, 2024 · In this tutorial, we covered one of the algorithms to detect cycles in directed graphs.
