Hello all,

I have created a sorting algorithm that is better than Quick Sort and even competes with Introspective Sort, but is constructed in a much simpler way.

I would like people to scrutinise the code, it is rather simple and shouldn't take long to look through. I want to know what people think of it. I have freely released the algorithm for anyone to use and develop further.

Please go to the following link to find out more:

Thanks.

Find the simplest proof and you have the ultimate truth.

A description of the algorithmm, and what makes it different from quicksort, would be nice (trawling through other peoples C sources isn't exactly a fun thing to do)

Hi everyone,

Please do not worry about looking at my code now.
I have had absolutely loads of excellent input and comments
from the message boards at these sites:
cboard.cprogramming.com
www.programmersheaven.com

Thank you anyway.

I looked at it (even though he found "better experts" ha! Wink | ;)

) As I understand it, he needs knowledge of the smallest and largest value, so he has a better partitioning at quicksort.

Hello,

I'm a newbie in computer programming.
I'm looking for a program help me to change file attributes(Created time,Modified time and last access) like FileDate By T.YogaRamanan.

Here is link :

http://www.codeproject.com/file/FileDate.asp[^]

But I want to ignore its user interface.(No Dialog box , No Text box)

I want to choose file as coding and change file attribute as coding too.

I have tried to read source code of FileDate above.
I still can't do.

Can you help me ? Smile | :)

Thank you.

Hi guys,
I 'm a student of computer science from Indonesia
and newbie in vb6 programming. please, help me to
learn the algorithm of vb6. the following is algorithm
question.

1) Present the prime number between 1 up to 10 that use
"Mod" and "Print" function. the Object is only 1 command
button.
Note: forbidden use "int" function

thank's for helping me.

your sincerely

Which part don't you understand? Ask a specific question, otherwise people here aren't going to do your homework for you.

Lately it seems like most of them come from third world countries where the powers that be want to ship US jobs. They're too lazy to even try to do their homework and they get rewarded for it.

Are you sure they really are in the US? Could be somewheres else in the world and making it look like they are in the US...

They can go ahead and do so. Any company that feeds these people will be in for a rude awakening when they find out their IT staff is so incompetent they leech off of people like us.

well, looks like no one here will help with the homework...
try this

private sub Commad1_click()
dim i as integer
for i=2 to 10 'why 2 cos 1 is not prime number
   if i mod 2 =0 then debug.print i
next i
end sub

Because most of us here don't do people's homework for them. Your code does not work 100%.

ups my mistake, the code suppose to be something like this, sorry.. sorry..

for i=2 to 10
if i mod 2<>0 then debug.print i
next i

Hi I have spent the day looking at implementing RSA on the client side with javascript and on the server side with C#.NET.

I think I am overlooking something very simple and this is my problem. To make a key of 1024 bits requires a datatype to store it in. What datatype should i use, i considered byte[] but surely byte[]*byte[] is undefined (to create the key).

Any help will be greatly appreciated

Thanks

Dan

You need to find a library for integers of arbitrary length or write one yourself.

Cheers,

Write or find the class that will handel the 1024(or biger) bit long number.
if write see some algoritms like:
1) Baret reduction
2) Montgomeri multiplay
. . . .
you will ned them in class.
[ It will better if you write class]

Costing terrain paths

My new project, I'm working on some path-finding algorithms for little AI
people. I have a grid of terrain heights and I have a pathing algorithm. The
trouble I'm having is how to weight the movement cost from one square to the
next. If moving across level terrain from one square to another is 1, how do
I cost uphill and downhill travel? I'm kinda stumped.

Also, moving diagonally is technically 1.41 in distance, should I cost it as such or just leave it as one for simplicity's sake? What are the pros and cons?

Any thoughts?

I think you should leave it as 1.41, otherwise you'll have funny results Smile | :)

Regarding height, maybe a cost formula like sqrt(deltaX^2 + deltaY^2 + (k*deltaZ)^2) might do Smile | :)

You could change the k coeff if climbing is more or less expensive than moving horizontally.

Smile | :)
