5 | //TODO parsing quotes/neurons seems too relaxed, for example the genotype aag"S""acalaaaafbc is considered valid |
---|
6 | //TODO Same with numbers: "----1.23" is valid |
---|
7 | //TODO reconsider: Horizontal gene transfer - copying a single random gene from each parent to the beginning of the other parent: should the gene be copied (seems to cause bloat!) or rather moved? |
---|
8 | //Neurons ("N") can grow even without using quotes and providing neuron classname in the genotype, for example aaaaabbccvaaapdgfddaalaandwddbaajt (this works likely as designed, but investigate and reconsider); also valid neuron definitions inside the genotype are sometimes not expressed |
