Agent 'Tom' starts
with belief that the coin is
good (

persuaded by the evidence
that the coin is double
headed. Note that the

Running the Program
The belief revision program that implements this model was run using our simple
example for three agents. In this simulation the agents have no communication with
each other. Their flexibility and receptivity (Sect. 6.2.1 and 6.2.2) was 0.25 as in our
illustrative example. However, all agents had access to all the experiments (two in
this simple case). The agent 'Tom' started with the 'belief' of 0.8 in 'good coin' and
a belief of 0.2 for a 'double-headed coin'. A typical run is shown in (Fig.
6.1
) where
Tom's overall confidence level falls at first then rises as more evidence is obtained.
Figure
6.2
shows agent 'David' starting with no bias. The number of cycles needed
to develop a suspicion that the coin is double headed varies but is typically about
eight cycles.
