Hi,
when i run my program, it shows this
"Exception in thread "main" java.lang.NullPointerException"
but my array doesn't not contain any null value, how can i check if the array is null or not,...

Because my x and y is a double value, is it i can passed a double value into it? i want to be more accurate, so i want it to be a double value for x and y.

The file contains:
1 2 50
1 3 60
1 4 70
2 3 80
2 4 40

i don't really understand unit vector, so i don't know how to calculate this, can anyone please help me to solve it?

A(10,0), B(5,8.7) find the unit vector v1 n v2, also find a unit vector w,...

Thank you for your explanation

yea, they have the same distance, so Prim's algorithm will choose which path first? If we start the tree from A, so the next one is B, C or D?

For prim's algorithm, if a vertice have the same weight to other vertices, so which one will it be choosen to put in the tree?
For example

A to B is 3
A to C is 3
A to D is 3
B to C is 3
B to...

Hi
Does anyone have the code of Delaunay triangulation?
Thank you

yes, x and y


after point 1 is projected, the right distance is the distance between point 1 and point 2 is the distance in the original space.


For example
Point 1 is (0,0)
Point 2 is...

Yea, the 3rd point is equidistant from 1 and 2, so the 2 solutions are a positive and negative y, is it? then i will take the positive one. But how can i do this?

The algorithm is
Pick a point and put it at the origin (0,0)
Put the second point to the right distance away from the 1st point (0, distance(Point 1, Point 2))
The 3rd point is the intersect of...
