Parsimony of results obtained with different heuristic approaches. All 96 input tree samples were analyzed using the tabu search implemented in AllCoPol, the permutation approach proposed by Oberprieler et al. [8], and the PhyloNet command InferNetwork_MP. For comparison, random solutions, from which AllCoPol starts its optimization, were evaluated. The scores obtained with InferNetwork_MP have been rescaled (multiplication by 100) because, if multiple gene trees per locus are provided, AllCoPol in its current version sums up their number of extra lineages, whereas the former by default uses their average
