Hi Cheng-Man,

Excellent work! I have a few questions regarding the flow shop problem.

1. What can be considered the state of art algorithm in flow shop problem and is being applied in the industry?
2. Have you also read http://citeseerx.ist.psu.edu/viewdoc/download?doi=10.1.1.65.5892&rep=rep1&type=pdf and what's your opinion about this?
3. What is the most challenging part of this problem now, is it the speed or the accuracy for finding the best solution?

Thank you!

Tony
