(*A(-(*AA)(sqrt A))) fitness:1
(/A(/(/AA)(/AA))) fitness:3
(+A(*(sqrt A)A)) fitness:0
PS.sqrt為開根號的意思, ex:A = (sqrt(*AA))
Since the fitness measure is a function of the data points we want to explain,
we define fitness as the number of output of the program that come within
20 per cent of the correct output values. We use this definition to create the
fitness measure of this initial population, to build crossover and mutation
operators that can produce further generations of programs, and to determine
termination conditions.
請問,fitness的定義為何?
我看了定義後,似懂非懂,但無法理解為何上面三個前序表示式的fitness值分別為1,3,0
請各位先進高手專家,不吝賜教,謝謝,感激不盡!
