WebSteiner tree problem classes by building several trees, performing local updates, and combining the best trees efficiently. As the initial tree-constructing heuristic, they suggest using the short-est-path heuristic (SPH). 2.2 Alternative Steiner tree approaches In recent years, a lot of deep learning models have attempted to solve hard ... In combinatorial mathematics, the Steiner tree problem, or minimum Steiner tree problem, named after Jakob Steiner, is an umbrella term for a class of problems in combinatorial optimization. While Steiner tree problems may be formulated in a number of settings, they all require an optimal interconnect for a given set of objects and a predefined objective function. One well-known variant, which is o…
