Declaration
void __stdcall nbrhdCCDM( void (*fitness)(float *, int), // fitness function bool symmetric, // symmetric links? float (*probLink)(float,float) // link probability function );
Parameters
Remarks
This function is available through the API. It can be called within the model-supplied routine onSimCreate to generate an arbitrary network, as described by [caldarelli02]. Although designed with scale-free networks in mind, it is able to generate many random networks. Along with the parameter symmetric the function nbrhdCCDM takes two functions as parameters:fitness
fitness is the name of a function with the following declaration:void fitness( float *fit, // pointer to array fit[0..agentCount-1] of type float int agentCount // number of agents in simulation );The fitness function takes in an array fit[0..agentCount-1] of floats and fills it with fitnesses sampled from a random distribution. On completion the elements of fit[] are randomly assigned to agents, in order to construct the network as described in [caldarelli02].
probLink
probLink is the name of an optional function with the following declaration:float probLink( float f1, // fitness of first agent float f2 // fitness of second agent );The probLink function calculates the probability that the second agent is a neighbour of the first if they have fitnesses f1 and f2, respectively. If symmetric=true then it is assumed that probLink(f1,f2)=probLink(f2,f1). The probLink parameter is optional in nbrhdCCDM, if not supplied probLink(f1,f2)=f1*f2 is assumed.
