Plot Pareto front evolution across generations — plot_pareto

This function visualizes the evolution of the Pareto front across generations in a multi-objective optimization context. It creates pairwise scatter plots of the objective values, highlighting the points on the Pareto front for each generation.

Usage

plot_pareto_generations(calib, generations = NULL)

Arguments

calib: dataframe; output from read_calib
generations: Optional vector of generations to include in the plot. If NULL, all generations are included.

Value

A ggplot object showing the evolution of the Pareto front across generations. Each point represents a run in a generation, with points on the Pareto front highlighted and colored by generation. The best parameter set (with the lowest 'fit' value) is highlighted in red. The axes are on a log scale to better visualize the distribution of objective values.
