The initial of max_strategy_dict value

[darren1231]

Thanks for your great contribution. I look detail in the algorithm of AMC code and I found it would create a max_strategy_dict at first and fill in the following value depend on the preserve ratio I set. lbound = math.log(FLAGS.cp_preserve_ratio + 1, 10) * 1.5

I can't figure out why would be this formula. Can you explain why? If you could, I would very appreciate.
