More precisely, in the first problem, called ., we are given an incomplete genome . and a complete genome ., and we look for the insertion of missing genes into . with the goal of maximizing t

The problem of finding . totally independent spanning trees (KTIST) or proving that no such trees do exist is NP-Complete. We investigate KTIST and an optimization p

We study several problems in the framework of classic complexity and approximation for which the compatibility graph is bipartite (star, chain, .). In such context, we design efficient polynomial-time approximati

To tackle the problem a two phases hybrid heuristic combining a mixed integer non linear solver and a local branching procedure is developed. Computational results, performed on literature instances, show that th
