软件简介

Evolve 是一个用 Objective-C 编写的演化仿真引擎。

示例代码：

- (void)evaluateFitnessForPopulation {    
NSArray *organisms = self.evolutionManager.population.organisms;    
for (Organism *organism in organisms) {        
   NSString *genomeString = organism.genome.sequence;        
   NSInteger geneSequenceLength = genomeString.length;        
   NSInteger correctCharacters = 0;        
   for (NSInteger charIndex = 0; 
      charIndex < geneSequenceLength; charIndex++) {            
      if ([genomeString characterAtIndex:charIndex] 
      == [kTargetString characterAtIndex:charIndex]) {
                correctCharacters++;
            }
        }

        organism.fitness = correctCharacters;
    }
}
