Finding Colorful Paths in Temporal Graphs

Riccardo Dondi, Mohammad Mehdi Hosseinzadeh

The problem of finding paths in temporal graphs has been recently considered due to its many applications. In this paper we consider a variant of the problem that, given a vertex-c…

The Longest Run Subsequence Problem: Further Complexity Results

Riccardo Dondi, Florian Sikora

Longest Run Subsequence is a problem introduced recently in the context of the scaffolding phase of genome assembly (Schrinner et al., WABI 2020). The problem asks for a maximum le…

Top-k Connected Overlapping Densest Subgraphs in Dual Networks

Riccardo Dondi, Pietro Hiram Guzzi, Mohammad Mehdi Hosseinzadeh

Networks are largely used for modelling and analysing data and relations among them. Recently, it has been shown that the use of a single network may not be the optimal choice, sin…

Complexity Issues of String to Graph Approximate Matching

Riccardo Dondi, Giancarlo Mauri, Italo Zoppis

The problem of matching a query string to a directed graph, whose vertices are labeled by strings, has application in different fields, from data mining to computational biology. S…

Reconciling Multiple Genes Trees via Segmental Duplications and Losses

Riccardo Dondi, Manuel Lafond, Celine Scornavacca

Reconciling gene trees with a species tree is a fundamental problem to understand the evolution of gene families. Many existing approaches reconcile each gene tree independently. H…
