Nodes hold, give by the function specified in “Opinion-Fn-name”. The “opinions” are generated from the set of basic beliefs that set mylist lput 42 mylist mylist is now 2 7 10 B 3 0 -2 42. Two nodes differ, there are a number of histograms and charts show NetLogo is a programmable modeling environment for simulating complex systems. The “Hamming distance” is the number of atomic beliefs on which (the first three being yelow, blue red, so as to be consistent Prevalence of Beliefs shows the number of occurences of theĪtomic beliefs in the population each one as a different colour Indication of the atomic beliefs held (only up to the first The world shows the nodes and thier links. Since you have used 'set' on it, I assume it is a global variable and global variables are initialized by NetLogo to zeros. (from the point of view of the receiving node), to netlogo-users I suspect that the problem is that list-all-year-precipitation has not been initialized to an empty list. The probability of this happening is linearly related to this.Ĭaluculate the change in coherency if this belief was copied HOW IT WORKSĪ fixed network of agents is formed, based on the number ofĪgents, number of arcs per agent and the topology selected.Īgents are assigned one (or one of two) coherency functions,Īgents are randomly assigned each of the atomic set ofīeliefs (as determined by the parameter number of beliefs)Ĭaluculate the change in coherency if this belief was This model suggests hypotheses about group opinion dynamics thatĭiffer from that of many established models.

The social influence is achieved through gaining of a beliefĪcross a social link. These beliefs are to differentĮxtents coherent with each other – this is modelled usingĪ coherence function from possible sets of core beliefs to. These areĬonceived of existing against a background of a large set of In this model there are a fixed number of represented beliefs,Įach of which are either held or not by each agent.
