- $\begingroup$ Thank you for your reply. I agree with what you mentioned, this function is extremely instable and needs serious attention, but I am wondering how to do this. You actually changed the function completely in this example, while I need the original function to be minimized. Moreover, even after rescaling for this function, I think if we can use more CPU cores (when the number of variables is very large) it is better than using one core. If you like to check the complete form of the function for 75 dimensions, please have a look at Edit 4. $\endgroup$mak maak– mak maak2012-09-26 05:17:30 +00:00Commented Sep 26, 2012 at 5:17
- $\begingroup$ @makmaak, I'm afraid I don't know much about this sort of thing. I had a look at your full function in Edit 4, but couldn't find a good approach to improve the stability. Good luck with it... $\endgroup$Simon Woods– Simon Woods2012-09-30 14:38:11 +00:00Commented Sep 30, 2012 at 14:38

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. list-manipulation), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
