Eng.) - Asian Institute of Technology, 1984 Summary: A Special Purpose Algorithm for Solving The Weighted subtree Problem The Weighted Subtree Problem (WSP) is the selection of an optimal tree out of a given network such that total edge costs are lower than a given budget value. Optimality refers to the overall utility of the subtree ; this utility is the sum of the utilities of the included vertices. Solution techniques for WSP are heuristic or make us e of integer programming. In this study a special purpose algorithm of the branch and bound type is developed. Its performance is tested on computer and comparisons are mad e with a heuristic approach.
