> # This example illustrates how to tune the parameters of the simulated
> # annealing algorithm (SANN) provided by the optim() function in the
> # R base package.  The goal in this example is to optimize instances of
> # the following family:
> # f(x) = lambda * f_rastrigin(x) + (1 - lambda) * f_rosenbrock(x)
> # where lambda follows a normal distribution whose mean is 0.9 and
> # standard deviation is 0.02. f_rastrigin and f_rosenbrock are the
> # well-known Rastrigin and Rosenbrock benchmark functions. In this
> # scenario, different instances are given by different values of
> # lambda.
> #######################################################################
> ## First we provide an implementation of the functions to be optimized:

+   tz <- z[2:d]

+ temp "" r (0, 100)
+ '
> 
> ## We use the irace function readParameters to read this table:
