MC 5.5 Beta 4 - where has Offspring Number gone?

geektrader · Postby **geektrader** » 11 Aug 2009

Hello,

in MC 5.5 Beta 4 the "Offspring Number" (one or two) in the Genetic Optimizer has disappeared for user-choice and now seems to be fixed to "Two". However, I´ve always used "One" with better results for the Offspring Number. Can you bring that option back please?

Thank you.

We had to remove it to make GA multicore-compatible. Why do you think “One” works better?

Interesting, you mean multi-CPU-core compatible? Well, I´ve used "One" and it still always used all my 4 cores of my CPU most of the time.

One did bring better NetProfit values quicker than Two, whyever that is.

The previous revision of the GA optimizer couldn't use more than 1 core by definition. This is why we revised it. Now it uses all cores.

Yes, we had a thread about that, about that GA only used 4 cores at the start, then only 1 after a few percent of optimization. You are indeed right that it uses all 4 cores now all the time, VERY nice! Thank you.
