For C/C++ or assembly? What PIC family?

Well, for C with the PIC18 family I would sugest The MPLAB C18 Compiler. I don't think it is GPL, because it is a comercial product sold by MICROCHIP. I consider it to be moderately priced (around 350 EUR), and I've used it and it is good. It has some bugs, but very easy to find and work around. You can find it at http://www.microchipdirect.com/productsearch.aspx?Keywords=SW006011[^].
This is not a C++ compiler. For that I don't know any products from personal experience.
I hope this helps,

I was looking for an alternative to microchip that I can build into a personal project. Being commercial, microchip doesn't lend itself well to that objective.

From the news page:
I only had one number theory class as an undergrad and we didn't talk about Mock Theta functions, but some researchers at UW apparently have made some major breakthroughs in Mock Theta function theory:

Hello everyone,
I am in search of an algorithm to find the most appropriate division technique of an area.
For example; I have 3 100x500 cm of sheets and I want to get 15 50x40 cm, 2 100x100 etc. sheets. So I have to divide these 100x500 cm sheets into smaller parts. But when I -let's say- try to get 15 50x40 cm sheets from only one 100x500 cm sheet probably there will be a loss (500 mod 40 != 0).
So I have to use a combine of 50x40, 100x100 etc. sheets.
Also there isn't a must to only use quadrangles. Polygonial sheets may also used.
So is there an algorithm to get the desired number of different area shapes from a number of main shapes with less loss ?
Thanks for your helps and best regards.

IIRC what you're describing is an NP complete problem.

Sorry about my English I am not good with abbreviations. So what do you mean by IIRC and NP..

I think you mean "nondeterministic polynomial".

sorry. IIRC is short for If I Recall Correctly, and is internet slang for I think this is right, but am not certain.

But at least there must be a subset of the NP, that is deterministic.. Am I wrong ?

There is, it's the set of problems called P. That's the sort of problem that can be done in at worst polynomial time on a normal computer.
Your question appears to indicate a bit of a vocabulary/jargon problem.
P is the set of problems that can be done in polynomial time on a dterministic turing machine. All normal computers are deterministic turing machines.
NP is the set of problems that can be done in polynomial time on a nondterministic turing machine. A nondeterministic machine guesses the correct solution (the first time, every time, in a nonexplainable way) and then proves that it is correct. A deterministic turing machine can simulate a non deterministic one, by trying each possible solution in sequence. This takes exponential time. A quantum computer is capable of directly running multiple data sets at once, but the fastest QC ever built is still no faster than a normal machine due to the low maximum qbit count it can work with.
It's believed, but not proven than P is a subset of NP, but that the two are not equal.
Depending on the problem, and conditions applied to it, there may or may not be a solution in P that can give a reasonable approximation with a known worst case error. Except for well known problems the approximations are unlikely to be published anywhere except in academic journals.

Really thanks for the explanation. So if we return to the point is there a way to "guess" or "approximate" the most proper division technique ?

probably, but given the lack of response I don't think anyone posting here is aware of one. If you can't find anything via google you'll need to do a journal search for papers on the subject. I don't know if CS journals charge for online access or not. If so, it may be cheaper to visit the library of a major college/university than to buy access.

Ok, I will give a try, and if get a result I will share it  . But at least, which keywords should I use in search? Any ideas?

Yep. Following the link from there to the knapsack problem confirmed my vague recollection that it was NP-Complete.

y=x-(xz)
what is the formula for finding the value of x from the given formula above.
Thanks

x = y / (1 - z)

Can any one tell me which is the best book of Advance Algoritham analysis
|
|

We used Introduction to Algorithms[^] (called "CLR" or "CLRS" for short) in my algorithms class, and it was a pretty good book.
TAOCP[^] is also supposed to be very highly regarded, but I have not personally ventured into that territory yet
