Short schemata are better than long ones and are called `building blocks'

• A short schema can better withstand cross-over and thus has a higher survival probability

  • For example, the schema **00**10 (short with stone pattern) is is very fit, but will easily be broken up

• Genetic algorithms are extremely efficient

  • in a population with 100 strings, about 1000.000 (n3) schemata will be evaluated
