The Floyd–Warshall algorithm can be used to solve the following problems, among others: • Shortest paths in directed graphs (Floyd's algorithm). • Transitive closure of directed graphs (Warshall's algorithm). In Warshall's original formulation of the algorithm, the graph is unweighted and represented by a Boolean adjacency matrix. Then the addition operation is replaced by logical conjunction (AND) and the minimum operation by logical disjunction (OR). WebFeb 22, 2024 · Although it is a correct solution the running time is way above of O(n^3) since in binary representation the greatest number in the modified matrix could use up to n*(n-1) bits. Then every add operation is Ω(n^2) and since Floyd-Warshall algorithm use O(n^3) add operations its running time in the worst case scenario is ϴ(n^5). WebThe shortest path problem involves finding the shortest path between two vertices (or nodes) in a graph.
