Direct search and optimla control

ABond — Tue, 28 Feb 2012 11:58:08 Z

Hi,

I would like to ask, what is the way to use the Direct Search (or other similar package) to solve not a static optimization problem for, say f(x_1,x_2), but the dynamic one, say for f(x_1(t),x_2(t),t)?

I think there must be the way of adapting the algorithm for that.

Any ideas welcome.

Best

Find own question

Cannot find own answer in

via searching in my answers. Is it because original message is too old and thats why should be so?

How look for command to do specific task?

tieuvodanh — Sat, 05 Nov 2011 16:57:15 Z

Dear,

How could we know which command to use to do a specific task such as: "convert boolean value to {1,0}" . I know we could use evalhf() but if we search with keyword "convert true false to 0 1 " in the Maple help then we may not find the right command

Using the Online Help is a solution but I want to know an offline solution since I am not always with the Internet. Did anyone wrote a summary sheet with the content such as : (i.e a list of all commands with keywords for searching)

Need help to search into a chunk of character.

lemelinm — Mon, 12 Sep 2011 16:37:11 Z

Hello to all,

I have a chunk of letters, numbers and others symbols like in this extract:

.....XRIH*zAv/(z*Bf3)+3*AkQ4xBpTbCYJVq6qCRRUYJy1aBvSjuQXp+zr6kmMEuNR+9*u9zugTalYwXJA*mBhaiM+8*WrkyyflSAs0JssjHLArZ+l5M1sWtcMznmkmu1+NmmSb7dsacr3qJkzQH*dE3yQlI0Ly2RGa1*Yr/ZlvZFCwCiQyVTQ2GflsnOBZTf05W4Ul35uZMHFxhy1tipPyK+iHfus/mJVhEeluq9vtVzEzwbPWav+w11/ii14f78yXqsqH+XU2m....

My goal is to be able to enter that chunk into Maple for character manipulation like searching if, for example, Qxp+zr6km is part of that chunk as is (and if possible his location). Since there is some "+", I can't define it with chunk :=. The source is a *.txt file. Maybe a readdata?

I am quite busy for the moment so is there someone kind enough to help me.

Thanks in advance

Is it possible to search a variable or any word or a command in a long worksheet

Thanks in advance

DirectSearch2 Function DataFit runs endless. But Searching with DirectSearch convergates!

wschrabi — Wed, 29 Jun 2011 11:14:02 Z

Hi Experts,

Here is my File. I use the DirectSearch2 Library.

Searching the Minimum works fine. (800 sec on i7 PC)

But the Datafit runs endless.

I tried to make the fit with min SSE that works, but why does DataFit not succeed?

Thanks for answering.

search files for specific text in a maple document

Christopher2222 — Thu, 26 May 2011 15:13:23 Z

I want to search maple files for specific texts within the file. What software will do this?

I recall some mention before about searching for specific texts in maple documents but I cannot find it.

mapleprimes search not working right

Christopher2222 — Thu, 31 Mar 2011 12:54:21 Z

If I search for something in mapleprimes then click on one of the selections, mapleprimes brings me to a page of many posts and does not bring me to the proper single post I expect to see. In fact the post or question I selected does not even exist in the next page mapleprimes sends me to.

Using Help with more than one search word (search phrase)

Ninetrees — Wed, 22 Dec 2010 16:01:44 Z

I don't seem to be able to get Help to respond to searches with more than one keyword...for example, I entered "date format" and received "No Matches Found."

Search misses

acer — Wed, 15 Dec 2010 03:40:05 Z

I notice that a Seach on this site for the word "cipher" fails to show this result as a hit. Why is that?

It is by no means the first time that a keyword Search on Mapleprimes has failed to return a hit for an old comment/post/answer of mine. I'd really like to know why there are so many such misses.

mapleprimes issues

pagan — Fri, 05 Nov 2010 18:47:14 Z

Aren't the acceptance numbers for various badges just way too high? Mapleprimes has only had 2 (one each) Good Posts at this date. And no Good Answers or Great ones of either type. But that's clearly not right, as the new site has had lots of great posts and answers. This same issue was raised long ago, and the admin response of long ago was that it would be revisited.

And there...

Search and feed pages

pagan — Thu, 16 Sep 2010 03:10:59 Z

I suggest that, if possible, the database or site-crawling used for Mapleprimes Searches not store pages ending in "/feed". It just adds to the chaff in search results.

I'd submit this as a Software Change Request, if there were a Mapleprimes checkbox on the form.

when I see a listing of my own posts/questions ...

Christopher2222 — Thu, 26 Aug 2010 10:21:25 Z

When I see a listing of my own posts/questions, I would rather like to see a listing much like in the format shown here www.mapleprimes.com/recent/all showing the postings less all the summaries.

This would speed up my searching if I, or anyone else, was looking for a particular post of mine, or someone elses.

Sorting Algorithms, now with sound.

dohashi — Mon, 23 Aug 2010 18:48:44 Z

Although I mostly post about parallel programming, my background is in algorithms and data structures. I have a soft spot for sorting algorithms. It probably started when I did some research into adaptive sorting as part of my coursework. Anyway, someone added sound to visualizations of different sorting algorithms. I'm not sure if it really helps explain the algorithms any better, but it does make them more interesting to watch.

Restrict search to a particular user

Joe Riel — Fri, 06 Aug 2010 14:43:51 Z

Occasionally I want to restrict a search of MaplePrimes to posts from a specific user. Is that possible?
