% tiny_04.graph
% A very small example of a graph
% with multiple vertex weights,
% stored in the METIS graph file format.
%
% The first non-comment line lists
% the number of vertices (7), edges (11), the value of FMT and NCON.
%
% FMT has the following meanings:
% 0 the graph has no weights (in this case, you can omit FMT);
% 1 the graph has edge weights;
% 10 the graph has vertex weights;
% 11 the graph has both edge and vertex weights.
%
% NCON, it appears, is the number of vertex weights. Normally,
% if vertex weights are used, there is only one weight per vertex,
% and it is not even necessary to list NCON in the input. But if
% multiple values are associated with a vertex, NCON must be listed.
%
% This graph uses vertex weights only. Vertex weights must be
% integers that are 0 or greater. For this data set, we will have
% three weights per vertex.
%
% The next line notes that vertex 1 has weights (1,2,0) and neighbors:
% vertex 5,
% vertex 3, and
% vertex 2.
%
7 11 10 3
%
% Three vertex weights, followed by all vertex neighbors:

1 2 0 5 3 2
0 2 2 1 3 4
4 1 1 5 4 2 1
2 2 3 2 3 6 7
1 1 1 1 3 6
2 2 1 5 4 7
1 2 1 6 4
