Figure 1: Pareto performance concept.
From: Metabolic efficiency underpins performance trade-offs in growth of Arabidopsis thaliana

Schematic illustration of Pareto performance. Two contending tasks are studied in one condition. The performance of genotypes is scored with respect to the two tasks and is depicted by the two axes. Each genotype is represented as a point in the resulting 2D space. The genotypes with an optimal trade-off between the two tasks form the Pareto performance frontier. The frontier arises due to systemic constraints affecting the performance, and separates the feasible from the infeasible region.
