Fig. 1From: Optimizing PCR primers targeting the bacterial 16S ribosomal RNA geneRepresentation of the efficiency, coverage and matching-bias optimization criteria for the Pareto front. Efficiency is represented on the y-axis, coverage on the x-axis and matching-bias using color shading. The initial primer-set-pairs are represented as squares; the primer-set-pairs after multi-objective optimization are represented as circlesBack to article page
