The setting of these parameters can largely influence the behavior and performance of an algorithm. How to best tune and control these algorithms is still a very challenging problem [7]. , a tuner, is needed. As with tuning a high-precision machinery, sophisticated tools are required. For tuning parameters in an algorithm, what tool can we use? One way is to use a better, existing tool (say, algorithm B) to tune an algorithm A. Now the question may become: How do you know B is better? Is B well tuned?

1 Random Variables Randomization is usually realized by using pseudorandom numbers, based on some common stochastic processes. The probability density distributions for random variables are commonly uniform distributions, Gaussian distributions, power-law distribution, and Lévy distributions. A random variable can be considered an expression whose value is the realization or outcome of events associated with a random process such as noise level on a street. The values of random variables are real, though for some variables, such as the number of cars on a road, they can only take discrete values.
