Randomization

Randomization is the process of making something random. It is remarkably difficult to make anything truly random, as most physical processes and human thoughts and actions are much less random than is commonly supposed.

Randomization is used extensively in the field of gambling. Imperfect randomization may allow a skilled gambler to have an advantage, so much research has been devoted to effective randomization. A classic example of randomization is shuffling playing cards.

Randomization is also required in the generation of random numbers for scientific reseach and cryptography.
