Q: We have two 30-year-plus birch trees that are doomed to be chopped down, but first we decided to see if you might have a solution. For years we used Cygon 2 E t…

This problem typically occurs as a subproblem of the Generalized Tree Alignment Problem, which looks for the tree with the lowest alignment cost among all possible trees. This is equivalent to the Maximum Parsimony problem when the input sequences are not aligned, that is, when phylogeny and ...
Most heuristics for the Steiner tree problem in the Euclidean plane perform a series of iterative improvements using the minimum spanning tree as an initial solution. We may therefore characterize them as local search heuristics. In this paper, we first give a survey of existing heuristic approaches...
If P(x1,x2)⊂T is a path, then d(x,P)=miny∈Pd(x,y), where d(x,y):x,y∈T, is the distance between points given by the length of the only path joining x and y, which makes T a metric space. We suppose that demand originates at the vertices of the tree, and we ...
