A phylogeny is described as a binary tree in which the leaves of the tree are the observed values of a given site in the different species and internal nodes take the values of the site for putative ancestral s
We then propose a new programming approach from discrete mathematics to construct tree stem form. Our method is based on an optimal connection of neighbor triangles for surface construction, which is created by locally possible combination of three digitized points on the stem surface. We compare ...
Meanwhile, there are many examples to show that in this case we can only restrict the maximum degree of the part with greater order in T, see [7]. However, if |a−b|≤2, the situation becomes very different and we hope to obtain a 2-packing with restrained maximum degree in both ...

Generally TMM has two characteristics: (1) the TMM formulae share similarity to the chain mechanics model in terms of topology structure; then TMM often is selected as a powerful tool to analyze the chain system. (2) TMM is adopted to deal with the problems of the discrete system, ...

All these algorithms have a run time, which is scaling exponentially with the number of nodes in the graph and are hence difficult to scale up to larger biological networks. They investigate all possible Steiner trees in order to find a minimal one. Examples of exact algorithms include the ...

If G is an interval p-graph with a representation in which no interval contains another properly, then G is a proper interval p-graph. The proper interval 2-graphs have been characterized via many properties and shown to be equivalent to many well-known classes of graphs (see [4, 12]) ...
