WebAug 7, 2024 · In this chapter, memetic strategies are analyzed for the Steiner tree problem in graphs as a classic network design problem. Steiner tree problems can model a wide range of real-life problems from fault recovery in wireless sensor networks through Web API recommendation systems. Webweights are one. Steiner trees are important in various applications such as VLSI routings [32], phylogenetic tree reconstruction [31] and network routing [34]. We refer to the book of Pr¨omel and Steger [38] for an overview of the results and applications of the Steiner tree problem. The Steiner tree problem is known to be NP-hard [26].
WebGiven a graph with nonnegative edge lengths and a selected subset of vertices, the Steiner tree problem is to find a tree of minimum length that spans the selected vertices. This … WebApr 1, 1993 · Even though the Steiner Tree problem has already been investigated intensively in the last decades, it might be further optimized with the help of new computing paradigms and emerging approaches.
http://profs.sci.univr.it/~rrizzi/classes/Complexity/provette/Santuari/steiner.pdf The Steiner tree problem in graphs can be seen as a generalization of two other famous combinatorial optimization problems: the (non-negative) shortest path problem and the minimum spanning tree problem.
