Villages.
A village agent accommodates human agents and serves as deposit
for their food resources. This agent is
lead
if a special organization (police or
CH
oce) requires it. The leader establishes the
social policy SP

.Eachmemberof
SP
determines the ratio of organi-
zational jobs (police,
CH
) per inhabitant offered to the population. Thus,
SP
allows to tune the resource given to the organizations, in order to balance orga-
nizational costs and benefits.
food
∈
: the amount of food stored by humans. Human agents storing their
bag
increase the value of
food
by the amount of their
bag
and set
bag
to 0. When
the village is lead, a portion (20%) of the stored food is spoiled by leaders (to buy
luxury goods). With this mechanism, we simplify the burden of sharing resources
via exchange, trade or redistributive economy (which can also be achieved with
our method, the redistributive economy being a pre-requisite of an organization
for instance). Thus, the salary of organizational workers is the ability to eat from
the common pot.

: the culture of the village. Without a leader, it is the average
culture
of its inhabitants, otherwise it is the

vector of the leader.
harvest tech level
: the food production eciency of the village (techno-
logical and environmental). When a human agent harvests some food, it puts
harvest tech level
units of food its bag. Empirically, the size of the society is cor-
related to the value of this variable. So, this variable is used in the experiments
to determine the society size. Its values ranges between 10 and 300.

Human Rules.
Figure 2 shows the main steps of the decision making process
of a human agent (individual behaviour).
Update life constants: energy
is decreased (starving agents are removed) and
culture
is randomly tilted (one of its items is set to a random value) with a
