Given a metric d on a permutation group G, the corresponding weight problem is to decide whether there exists an element Ï€ âˆˆ G such that d(Ï€, e) = k, for some given value k. Here we show that thisâ€¦ (More)

A hierarchical structure describing the inter-relationships of species has long been a fundamental concept in systematic biology, from Linnean classification through to the more recent quest for aâ€¦ (More)

Phylogenetic trees are a commonly used tool for representing the relationships between species in an evolutionary system, especially in evolutionary biology. A central task in the study of theseâ€¦ (More)

We investigate the computational complexity of finding an element of a permutation group H âŠ† Sn with a minimal distance to a given Ï€ âˆˆ Sn, for different metrics on Sn. We assume that H is given by aâ€¦ (More)

Evolutionary history of protein-protein interaction (PPI) networks provides valuable insight into molecular mechanisms of network growth. In this paper, we study how to infer the evolutionary historyâ€¦ (More)

Phylogenetic networks are a generalization of phylogenetic trees that are used to represent reticulate evolution. Unrooted phylogenetic networks form a special class of such networks, which naturallyâ€¦ (More)

Various topological indices have been put forward in different studies from bio-chemistry to pure mathematics. Among them the Wiener index, the number of subtrees and the RandiÄ‡ index have receivedâ€¦ (More)
