graph_diameter(1) Scilab function graph_diameter(1)
NAME
graph_diameter - diameter of a graph
CALLING SEQUENCE
[d,p] = graph_diameter(g)
PARAMETERS
g : graph list
d : integer
p : integer row vector
DESCRIPTION
graph_diameter computes the diameter of the graph g i.e. the largest shor-
test path between two nodes. The length of the arcs are supposed to be
integer (and the default value is 1). The output is the value d of the
length of the diameter and p is the corresponding path.
EXAMPLE
ta=[1 1 2 2 2 3 4 5 5 7 8 8 9 10 10 10 10 11 12 13 13 14 15 16 16 17 17];
he=[2 10 3 5 7 4 2 4 6 8 6 9 7 7 11 13 15 12 13 9 14 11 16 1 17 14 15];
g=make_graph('foo',0,17,ta,he);
g('node_x')=[283 163 63 57 164 164 273 271 339 384 504 513 439 623 631 757 642];
g('node_y')=[59 133 223 318 227 319 221 324 432 141 209 319 428 443 187 151 301];
g('node_diam')=[1:(g('node_number'))]+20;
show_graph(g);
[d,p] = graph_diameter(g)
show_arcs(p);
