Matchstick Graph Editor

Recently I created  a specialized graph editor for matchstick graphs like the Harboth graph. It is not a fancy application but it works:

Try it out and load the data of the harboth graph into your editor!

Question: What is the minimal 1, 2 and 3-degree-matchstick graph in 2D?

Requirements:

  • In a 3 degree graph every node has exactly 3 edges
  • It must be a planar graph (edges can only intersect at the nodes)
  • Length of each edge is the same
  • Be the first and link to your matchstick.dat file(s)
  • Think about solutions for 1, 2, 3 and 4 degree matchstick graphs in 3D (easier than 2D)

Prizes: Win Experience and be listed here as a winner😉 !

Conclusion

Getting starting and done was easy and fast within some hours. But debugging and writing tests in JavaFX (1.2 or 1.3) with NetBeans is not that good as described earlier:-/

    the way you characterize minimal matchstick graphs i’d say the empty graph is a viable answer for any degree.

    I am nearly always talking to myself at this (my) blog so … well😉

    > the way you characterize minimal matchstick graphs

    com’on, I could give a mathmatical definition here … but I hoped to got smart answers … aeh moment, your answer is smart🙂

    but did you find solutions != empty graph?
