What is the difference between Genetic optimization and Complete optimization

It is the explanation about: MetaTrader 5 Help → Algorithmic Trading, Trading Robots → Optimization Types

My experience (about total passes, about optimization time and for how much/costs):
post #65, post #66, post #67 and post #68 

Thank you so much for your continuing support, Sergey. 

It looks complete optimization is better for quality. 

I'm finding some way to do a real complete optimization test for total pass. 

Do you have any idea? 

I had some advice in other post, but I didn't really understood.

Thank you in advance and kind regards

They were thinking that you are the coder, and suggested to you to use dll for "real total pass result" in case you are using many generic optimizations (for example).

As to me so I was optimizing using pre-selected pair/symbol on pre-selected timeframe with pre-selected broker (because the result of optimization may be different from one broker to an other one). Why pre-selected pair/symbol with pre-selected timeframe? Because I used EAs which was coded based on manual trading systems which I traded manually so I already knew the pair and timeframe.

In this way I can select the settings for some pair on some timeframe with the broker.
In case I change the broker so I will make the other optimization.

Thank you so much, Sergey. 

Is that mean I could do a total pass test by code?
