- Road map of Hungary (in LGF format)
- There are three versions:
- Undirected version (.lgf.zip) Both one way and two ways road are represented by one single edge
- Directed version (.lgf.zip) The two way roads are represented by tho oppositely directed arcs.
- Strongly connected directed version (.lgf.zip) The largest strongly connected component of the previous file. Here is a printable .pdf version: hun-conn.pdf
- The description of the LGF format can be found here: http://lemon.cs.elte.hu/pub/doc/1.3/a00002.html
- The file contains the following attributes:
- in the @nodes section:
- label: the node label, >= 1 integer numbers
- lat: the latitude of the node, floating point number
- lon: the longitude of the node, floating point number
- in the @arcs section:
- length: The length of the road, in meter (integer number)
- maxspeed: The maximum allowed speed , in km/h (integer number)
- in the @nodes section:
- There are three versions:
- Planar graph test examples: planar-graphs.zip
- The file contains the following attributes:
- in the @nodes section:
- cost: cost of the nodes (integer number)
- label: the node label, >= 0 integer numbers
- coordinates_x and coordinates_y: the coordinates of the nodes, floating point number
- in the @arcs section (in *-c.lgf files only)
- capacity: capacity of the arcs (integer number)
- cost: cost of the arcs (integer number)
- in the @nodes section:
- The file contains the following attributes:
- Homeworks
- Is there a polynomial algorithm for finding the 1002 long sequence surely opening any three digit door?
- Or just a short proof that it exists?
- Find the two places in Hungary that are the farthest away from each other.
- Find a small cardinality/cost vertex set covering all edges in the above graphs.
- Is there a polynomial algorithm for finding the 1002 long sequence surely opening any three digit door?
