From: The optimality of the standard genetic code assessed by an eight-objective evolutionary algorithm
The plot of the discriminant function analysis based on the eight objective functions for the standard genetic code (SGC) as well as the codes minimizing (Best) and maximizing (Worst) the objective functions under the block structure (a) and unrestricted (b) models. The discriminant analysis was done in Statistica (StatSoft Inc. 2018, version 13, https://www.tibco.com/products/tibco-statistica)
