This is in fact a clustering problem - you wish to cluster n airports to gi groups where each group centroid is a gas station coordinate.
Simplest (but maybe not best) method is to use the K-means...

"Lists have the important property that insertion and splicing do not invalidate iterators to list elements, and that even removal invalidates only the iterators that point to the...

If you *KNOW* there are exactly n/2 1's and n/2 2's, then why sort ?
Go over the array and assign 1 to the first n/2 elements and 2 for the rest.
Exactly n assignments and no need for comparison......

Basically you are rearranging each of the matrices rows according to the sorted ordering of a given column in a given matrix.

You just need to figure out what is the new row index of each of the...

Mathematica is also a good option, in my experience.

Computationally speaking, just emulating the program run and counting the number of steps is not so hard - but if a program with finite run-time may still run for a VERY long time depending on the...

Seems to me that a ternary tree could be used the same way as a binary tree is used - by, for example, ignoring the right-most child (keeping it NULL) of each node, and considering the left-most and...

As I remember, the number of moves required is (2^n) - 1,
anyhow, this number is Theta(2^n) if and only if it's O(2^n) and also Omega(2^n).

Go back to the mathematical definition of the big-Oh...

You can use [ code ] tags to wrap around your code - '#' icon in rich edit mode.
The reason your code goes into an infinite loop is that the for loop exit condition is that i > 255 (since if i <=...

Well, that's how cin works.


Good idea! (except for the 'but that seems too complicated' part :)).
If you try doing as you suggested, maybe it won't seem so complicated.

To find the ratio between your "world" coordinate units to the cost/heuristic function units, just look at the distance cost between 2 adjacent points relative to the "coordinate" distance between...

This is because this is not C++ or C code at all. This is bison(or yacc) BNF input format.
Maybe this yacc calculator example will prove handy ?
I am absolutely *not* the master of bison(or yacc),...

Right.

Radix Sort can give you run-time complexity of O(n).

Do you want to find two numbers X, Y, where X is a number from the first array and Y is a number from the second, such that X + Y = S, and S is some predefined value ?

Are the arrays sorted ?

Or you can do this:


#include <stdio.h>
main(int t,char _,char *a)
{
return!0<t ? t<3 ? main(-79,-13,a+main(-87,1-_,main(-86, 0, a+1 )+a)):1,t<_?main(t+1, _, a ):3,main ( -94, -27+t, a )&&t==...

bool Mob::checkLeader(Mob* L)
{
if(leader != NULL) //leader exists
{
if(leader != L) //leader is not me
{
if(checkLeader(L)) ...

Yes, it is.
Think about how you can sum the value of a path starting at index i, given the sum of the path starting at index i-1, in O(1):
161 = 97 + 32 + 32
164 = 32 + 32 + 100

164 = 161 - 97...

This makes it even simpler.
You can think of your segment as having only ranges which are 1 unit in length by dividing each range with weight w of x units length to x ranges with weight w each.

This seems like a rather straight forward problem, though some optimizations come to my mind. There exists an O(n) algorithm to solve this problem, where n is the total number of units.

In general, you can use the Flood Fill algorithm in order to find all pixels with the same color, starting from a given pixel.

Hi,

I'm interested.
I have 5 years of commercial development experience in both C++ and C#.
You can PM me if this is still relevant and we will close the details (I couldn't PM you since you...

If I put code lines which does the majority of the computation in your example code, it would be the following lines:


cornerSlope = (ymax - p1y) / (xmin - p1x); //in clipEnd()

If we're going for an overkill, there are many funny ways of doing stuff ;).
