NAME

+

+ bb_fitness - Grow a random graph with the fitness model +

+ +

SYNOPSIS

+ +

bb_fitness N m n0 [SHOW]

+ +

DESCRIPTION

+ +

bb_fitness grows an undirected random scale-free graph with N +nodes using the fitness model proposed by Bianconi and Barabasi. The +initial network is a clique of n0 nodes, and each new node creates +m new edges. The probability that a new node create an edge to node +j is proportional to

+ +
    a_j * k_j
+
+ +

where a_j is the attractiveness (fitness) of node j. The values of +node attractiveness are sampled uniformly in the interval [0,1].

+ +

PARAMETERS

+ +
+
N

Number of nodes of the final graph.

+
m

Number of edges created by each new node.

+
n0

Number of nodes in the initial (seed) graph.

+
SHOW

If the fourth parameter is equal to SHOW, the values of node + attractiveness are printed on STDERR.

+
+ + +

OUTPUT

+ +

bb_fitness prints on STDOUT the edge list of the final graph.

+ +

EXAMPLES

+ +

The following command:

+ +
    $ bb_fitness 10000 3 4 > bb_fitness_10000_3_4.txt
+
+ +

uses the fitness model to create a random graph with N=10000 nodes, +where each new node creates m=3 new edges and the initial seed +network is a ring of n0=5 nodes. The edge list of the resulting +graph is saved in the file bb_fitness_10000_3_4.txt (notice the +redirection operator >). The command:

+ +
    $ bb_fitness 10000 3 4 SHOW > bb_fitness_10000_3_4.txt 2> bb_fitness_10000_3_4.txt_fitness
+
+ +

will do the same as above, but it will additionally save the values of +node fitness in the file bb_fitness_10000_3_4.txt_fitness (notice +the redirection operator 2>, that redirects the STDERR to the +specified file).
