output_midi_data[0].write("output.mid")

Limitations

There are some basic limitations:

• My knowledge of Music Theory
  • It is really hard to understand it in such short period of time from very zero, therefore some results are not archivable by human reasons.
• Computationally-intensive
  • Because of the many possible options of chord for each place.
• Near-optimal solution
  • Due to algorithm definition a near-optimal solution can be found with it.
• Mutation
  • Sometimes it is not possible to get the best result because of random mutation.
• Evaluation
  • Evaluation function require an excellent knowledge of the task that this algorithm is going to solve, therefore some results are not archivable by human reasons.
