I guess, by know I got to know the answer myself! The mistake I initially did was, I neglected the |E| in O(|E|+|V|log|V|). In the worst case, we can consider O(|E|) to be O(|V|^2). But still, we treat |E| as a separate variable because, |E| <= (|V|^2- |V|)/2. Though there is an upper bound for |E|, it is still independent of |V|. I have explained this well in my blog: http://www.creativitymaximized.com/2015/10/shortest-path-algorithm-elaborated.html[^]

Hello,I understand Shell Sort definition but I can not understand
this C# code:
public void shellSort()
{
int inner, outer;
long temp;
int h = 1;<br />
while(h <= nElems/3)
h = h*3 + 1;
while(h>0)<br />
{
for(outer=h; outer<nElems; outer++)
{
temp = theArray[outer];
inner = outer;
while(inner > h-1 && theArray[inner-h] >= temp)
{
theArray[inner] = theArray[inner-h];
inner -= h;
}
theArray[inner] = temp;
} // end for
h = (h-1) / 3;<br />
} // end while(h>0)
} // end shellSort()
please help me thx!

Why don't you let the code show you how it works ?
Use the debugger ! You will see the code doing its stuff. Run the code step by step and inspect variables.

Why do you give me this link ?
I know how it works !

Quisiera saber quien tiene el algoritmo de Ford y Fulkerson , he estado buscando en varias paginas este algoritmo, pero no logro conseguir.Si alguien lo puede conseguir lo antes posible o hacerlo estaría muy agradecido.

This is an English language site. You'll get few responses for postings in other languages.

I would like to know who has the algorithm of Ford and Fulkerson, I've been searching several pages this algorithm, but I can not get. If someone can obtain as soon as possible or make it I would be very grateful.
Ford--Fulkerson_algorithm[^] on Wikipedia has an explanation as well as a Python implementation. For other languages, you're on your own...

A directed graph is called a unique-path graph if given vertices v and w, there is at most one path from v to w. Now, I am given a graph G in which there exists a vertex x that has paths to all other vertices. (The vertex x is not known to us initially) How do I check that G is a unique path graph in O(|E| + |V|) time?
Using the concept of strongly connected components, I can find the vertex x in O(|E|+|V|) time. How do I proceed after that? How does x help us in checking multiple paths between a pair of vertices?

What data do you have about the graph ? got a example ?
Have you tried something ?

Hi All,
I am trying to come up with an algorithm to get following three piece of information to plot a chart:
1. Start : Should be close to the minimum value of the dataset
2. Stop : Should be close to the maximum value of the dataset
3. Interval : Should be such that it will have "0" on the axis when interval traverses from minimum to maximum.
Example: dataset{-266,-17.6,0.5,2000,6000}
My final return values should be:
Start: 400
Stop: 6000
Interval:200
Note: Since start is 400 and interval is 200, we will have 0 as a point on the x-axis.
|
|
|
|
|
How did you choose 400 to be 'close' to -266? Plotting the values from 400 to 6000 in intervals of 200 is a simple straight line. Your question is not clear.
|
|
|
|
|
400 value is in example. I came up with those numbers to explain what I am trying to achieve.
Actually, I did figure this out.
Thanks.

Hi all!
when this impulse based equation can equal to zero:
w'=w+(j/I)*r*n;
n normal contact;j impulse;I inertia;

What is your question ?
And I guess more details will be welcomed.

as you know: https://en.wikipedia.org/wiki/Collision_response[^]
just that w will never be zero, and need always two points of contact to be;(the eqation above is elastic collision with rotation no friction)!

a triangle can never stand like this!(in a real world or can it!?)
see here(http://i.stack.imgur.com/o9P7V.png[^]
what if the ball was heading the center of the bar, the bar won't spin right!
but we know that a force in a direction in a center of mass mmake angular velocity zero right!
but this equation from wiki never make it until there is two points of contact, is that is!?

Ok, the wording is not obvious for not English native people.
A couple of sentences explaining what you are looking for will not arm.

Good day,
I have a DB, that have a 3000 strings and 40 integer columns, each of them describe something about 1 piece of product, for example, cost, resource, etc.
User type end sum for each column.
I need a feedback, what stack of 5 types of instruments fits max by each column to the user number.
For example, 7 hammers, 2 presses, 3 crowbar, 4 gloves, 5 glasses all together cost 154000 money, user input 150000, have a resource of 923000 hours, user input 920000 etc.
I don't know, how to google that question or use search for it, but if you can help me with it's name or, more of it, with building, i will release my end program under Open Source. Thank you very much for your time, sorry, if my English bad.

It is looking like HomeWork !
I think some details are missing in the problem to fully understand what is the request?
It look like a simple counting problem.
What have you tried ? What is your problem ?

Good day,
You can solve this problem by integer linear programming.![Rose | [Rose]](https://www.codeproject.com/script/Forums/Images/rose.gif)

It is more like counting things.
like making a list of all names, and counting each you see a name
and printing the top 5 names.
