WebThe longest path problem is fixed-parameter tractable when parameterized by the length of the path. For instance, it can be solved in time linear in the size of the input graph (but exponential in the length of the path), by an algorithm that performs the following steps: Perform a depth-first search of the graph. Let

POJ 3764 – The xor-longest Path Posted on February 22, 2012 Link It is a good idea to solve this or another similar problem before solving this one. This problem reduces to: given a number x and a set S with some other numbers in it, find such that x xor y is maximum. WebXOR has an identity: x ^ y = (x ^ z) ^ (y ^ z). Then we can transform the original question according to this equation. 1. create a source point (I used 0 directly for this question), …
