Hello everyone! I want to propose a problem from graph theory : ) Consider a connected graph G. Find all bridges and articulation points of G with an algorithm...
I have a table of distances between cities. I'd like to make a map based on it, but I haven't been able to find a formula for the coordinates of the vertices...
Hello, a fun little exercise is to derive a formula, assuming that two of the vertices lie on the x-axis, with one vertex at the origin. Then, vertex number...

Suppose you have a triangle with the base lying on the x axis with vertex coordinates (0,0), (x_1,0) where x_1 is rational. One of the other sides has...
As I understand your question, I could use (3.4) as the third vertex. The distance from that point to the origin is 5, so that's my rational length. If I set...

I was thinking of another problem relating to this, so I'll clarify it more. Fermat's Last Theorem states that a^n+b^n not= c^n where a, b and c are integers....

In this equation, I wrote j(mod(p_i)), this should read j(modulo (p_i)). I don't have the source code and I didn't have time to re- write it. It would be...
