For low values of the non-linear parameter
buyers never build-up any fidelity.
This is observed in figure 2 , which describes the dynamics
obtained with
= 0.8.
The daily profit of buyers averaged over all buyers and
over 100 days after a transition
period of 100 days, is 0.0502. This result is
lower than the average profit per transaction
for the buyer
. This is due to all those
occasions on which a
buyer visited an empty shop.
The daily profit of sellers averaged over all sellers and
over 100 days after a transition
period of 100 days, is 0.6532.
This result is
lower than 10 times the average profit per transaction
for the seller
(the factor 10 corresponds to
the average number of buyers per shop). This difference was also
generated indirectly
by buyers who visited empty shops since, at the same time,
some shops with supplies were not
visited, and this resulted in losses for their owner.

).
a The organization process is monitored by simplex plots
taken at times 10, 22 and 50. Even at time 50, agents
are still scattered around the barycenter of the triangle,
an indication of a disordered regime without preference of
any agent for any of the shops.
b Time plot of the order parameter y.
c Performance log of morning transactions in shop number 1.
The time charts display the initial quantity of goods
to be sold every morning, the remaining unsold goods
by the end of the morning, the number of customers, of those customers
refusing the proposed price (which soon falls to zero for
the present choice of a, b and
), and of those unsatisfied
customers who did not manage to buy anything.
The order parameter, y fluctuates well below 0.50 and thus
corresponds to randomly distributed .
This feature is also clear from the simplex plots of the
.
Figure 2 shows that the performance of shop number 1
exhibits large fluctuations. The same is true for the two
other shops.
