Resumo: Many methods in computational comparative genomics require gene family assignments as a prerequisite. While the biological concept of gene families is well established, their computational prediction remains unreliable. This talk will present a new line of research in which family assignments are not presumed. We study several family-free approaches in detecting conserved structures, genome rearrangements and in reconstructing ancestral gene orders. This leads to a number of interesting combinatorial optimization problems, some of which turn out to be surprisingly hard, others are easily polynomial-time solvable.
