Defining the problem in familiar terms is one way of asking the question 'How do we solve this?'. I went on to say we can then go on and express the problem in terms of plain english, I'm not dismissing plain english just tyring already to work out the problem in term I already understand - the question is this particular case is to myself, how to I work this out?

The Grand Negus wrote: algorithms are not limited in the ways that formulas are
Formulae are necessarily limited - thats the point surely? Also most algorithms depend on formulae to work (whatever language they might be written in), theres no getting away from them!
The Grand Negus wrote: First because there are too many strong but unnecessary ties to conventional math
Just because conventional math is used doesn't make it wrong - theres no need to reinvent the wheel 'just because', we can still use the useful features of the wheel like the fact that its round and still come up with something new. A new geometry will still need to use addition, multiplication etc to work.
The Grand Negus wrote: the paper stops short of practical applications
Of course it does - the guy is an academic!
If a system like you propose were developed, how do you imagine it is integrated into existing applications? Microsoft for example aren't going to incorporate it into Word just because its better and faster that any other method (if they did things like that we would all be running MS Linux by now!)

The Grand Negus wrote: Less than 10% of the routines in our 25,000 line development system involve formulas of any kind
I disagree - most algorithms will contain a formula of one kind or another even if it is simply "add 1 to the current position" its still a formula. Prove me otherwise!
The Grand Negus wrote: your contention that "most algorithms depend on formulae to work" is simply not true
Maybe if you had used more your development would have been a little more efficient!
The Grand Negus wrote: It's not addition and multiplication we object to; it's real numbers
And how in your 'graphics system' do you expect to be able to represent circles without Pi? Calculate the hypotenuse of a triangle without square roots? Do anything interesting at all without Sine and Cosine? Not easy without real numbers - of course you could scrap everything mankind has ever learned about mathematics since the dawn of time and start again, either that or approximate Pi to 3...
The Grand Negus wrote: "impedance mismatch"
You use this term all the time - when I was at school it was a term used by electronic engineers, I assume that you mean this in a different sense - maybe a certain kind of academic trying to communicate with us ordinary folk might be an "impedance mismatch"
The Grand Negus wrote: Teachers will be able to use the information, together with our Plain English development system, to introduce the next generation of "mathematicians" to this kind of constructivist thinking
My son briefly played with this kind of 'educational' software, Logo was it? For about 10 minutes before he got bored and moved on along with his friends to real programming C++, HTML etc, he's 10 now. The last thing kids these days are interested in is plain english - have you heard them speak?! Now think of a language based on emoticons and you might be on to a winner! (actually there's an idea...)

The Grand Negus wrote: You're not the guy for this project
You're kidding, right?
The Grand Negus wrote: I did. 90% of the routines in our development are void of anything that resembles a formulaic approach
Since when did quoting a single unsubstantiated figure constitute a proof? Maybe an example would help?
The Grand Negus wrote: and it can reproduce itself, on a bottom-of-the-line Dell, in less than three seconds
For what purpose?
The Grand Negus wrote: On page 97 of our reference manual there is an illustration of a sine-wave constructed from an integer-only polygon smoothed using integer-only math
Since I do not have access to your manual this can't be considered an example - again I only have your unsubstantiated claim that it is proof. I have no doubt however that you can draw very pretty pictures using only integers, but that still doesn't help you rotate a cube 33 and a third degrees around the X axis - a very real graphic 'problem'.
The Grand Negus wrote: We define a real programming language as one that can be used to conveniently and efficiently reproduce itself
Like C you mean?
The Grand Negus wrote: You should have asked about the difference between an "apparently intelligent" machine, and an "artificially intelligent" one
I know this one - 'artificial intelligence' applies to the machine, 'apparent intelligence' applies to the user of the machine, right?

Sounds like you may be wanting to use vectors to form lines. Such as in some advance CAD systems.

Whats all this got to do in a C# forum?
If a newcomer writes a question for languages/subjects other than C# he is banged straight.
Shouldnt this topic be discussed in more appropriate forums?

Please ignore my previous reply.
I accidentally got linked with this forum instead of C#.
Apologies for the inconvinience caused.

hey boy, that's physics, not math itself.

Correct - but you don't get far in physics without math, and without physics math is just an intellectual excercise, you draw the line between them, I suspect it won't be a straight one!! (probably a fractal)

I want to make my project (witch I did it with Matlab) I want to make it runs on any PC without the need of Matlab program to be on this PC.
in other words...I want to make my project an (.exe) file.
how can I do that please???

You will have to buy the MatLab compiler.

Check if "mcc" command works in your Matlab console.

I didnt understand
I wrote help mcc on my matlab command window....
I read what is written....
but how can I convert a matlab project to .exe file that dosent need matlab program to run...
note: I'm using matlab 6.5 or 7

you could ask in the matlab forums or help discussion.

mcc -m main.m
where main.m is the starting function (Entry point)of the project.
An exe file named "main.exe" will be created
along with other files and folders.
For further details google
with "mcc option for matlab".
Hope that helps you.

Can anyone tell me what kind of algorithm Tomtom and Garmin are using to find the shortest route in a huge data set as all roads on a continent?
Is it A*? In this case do they query the database in each loop?
Hope you understand what i mean.

usually commercial vendors use private, often patented algorithms for these things. This keeps the competition from directly redoing what they have done and selling it for less.

any easy and fast data mining algorithm any one knows?

To do what? There are a multitude of data mining algorithms each offering benifits in specific areas. You need to be more specific about what you are trying to accomplish.

Actually i have a huge data given to me and i have to identify let say all students name, address, reg.no, who belong to electrical engineering. what else pattern means, and i want to know the names of DM algorithm. also which one i can use more quickly and fast to understand as well as effective in limited time span.
