Hi! I'm writing a genetic algorithm in Python to cross the "parameters" in the above separate JSON objects. How would I go about doing this, I'm not sure how to retrieve specific name-value pairs based on the crossover index. Thanks!! :D

  • use the json module. What you presented is not valid json (you need another {} on the outside). – syntonym Jun 22 '16 at 14:55

  • Seems you have real-valued genotypes. Are you sure you want to do just a single-point crossover? That is usually a very bad approach when dealing with real numbers. Much better are crossovers based on random sampling, e.g. BLX-alpha. – zegkljan Jun 23 '16 at 05:33
