## Rosenbrock Banana function
Rosenbrock <- function(x){
x1 <- x[1]
x2 <- x[2]
100 * (x2 - x1 * x1)^2 + (1 - x1)^2
}
lower <- c(-10,-10)
upper <- -lower
r <- DEoptim(Rosenbrock, lower, upper)
summary(r) ## print summary of the DEoptim object
par(mfrow = c(1,2))
plot(r, type = 'b') ## plot the best members
plot(r, plot.type = "bestvalit", type = 'b', col = 'blue') ## and the best values
