A scaling algorithm solves a problem by initially considering only the highestorder bit of each relevant input value (such as an edge weight). It then refines the initial solution by looking at the two highest-order bits. It progressively looks at more and more high-order bits ...

Web13 May 2011 · In graph theory, a matching is a subset of a graph's edges such hat no two edges meet the same vertex. A matching is maximum if no other matching contains more edges. A trivial solution (exhaustive search) to the problem of finding a maximum matching has exponential complexity. WebThere are several algorithms to partition the nodes of a graph into SCCs, the main ones being the Kosaraju-Sharir algorithm [28], Tarjan’s algorithm [29], and the class of path-based algorithms [25,22,7,4,9]. In this paper, we present the veri cation of Gabow’s path-based SCC algo-rithm [9] within the theorem prover Isabelle/HOL [24]. Web24-4 Gabow's scaling algorithm for single-source shortest paths.
