% tiny_03.graph
% A very small example of an unweighted graph
% stored in the METIS graph file format.
%
% The first non-comment line lists
% the number of vertices (7), edges (11) and the value of FMT.
%
% 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.
%
% This graph uses vertex and edge weights.
% Vertex weights must be integer that are 0 or greater.
% Edge weights must be integers strictly greater than 0.
%
% The next line notes that vertex 1 has vertex weight 4, and is connected to:
% vertex 5 on an edge with weight 1,
% vertex 3 on an edge with weight 2, and
% vertex 2 on an edge with weight 1.
