The plot method for de-class objects gives a plot
of best and average fitness values found during the iterations of the
DE search.
# S4 method for de
plot(x, y, ylim, cex.points = 0.7,
col = c("green3", "dodgerblue3", adjustcolor("green3", alpha.f = 0.1)),
pch = c(16, 1), lty = c(1,2), legend = TRUE, grid = graphics::grid, ...)The method invisibly return a data.frame with the iterations and summary statistics for the fitness function evaluated at each iteration.
