Solving the Steiner Tree Problem in graphs with Variable Neighborhood Descent
The Steiner Tree Problem (STP) in graphs is an important problem with various
applications in many areas such as design of integrated circuits, evolution
theory, networking, etc. In this paper, we propose an algorithm to solve the
STP. The algorithm includes a reducer and a solver using Variable Neighborhood
Descent (VND), interacting with each other during the search. New constructive
heuristics and a vertex score system for intensification purpose are proposed.
The algorithm is tested on a set of benchmarks which shows encouraging results
