Material Balance - Third and Fourth Try

• Used a standard bit climber:

  • flip a bit
  • evaluate
  • if fitness is worse, unflip the bit
  • if we get stuck, scramble some number of bits and restart

• Performed even better

• Perhaps the problem is not as complex as we had once thought...?

• Used a modified bit climber:

  • flip bits according to changing probabilities

• 200x speedup over the original version

• Project now feasible
