Results
Figures 5 to 8 show the end value of the (
valence
) for each problem. In all cases,
the value obtained by the proposed deliberative model is significantly better than the
reactive one. This is due to a better employment of the
buy
action and the reduction
on
go
actions of the deliberative model. The reactive model always tries to satisfy the
need associated to the most dominant drive at each time. So, for instance, if reducing
the current dominant drive requires drinking, and there is no drink in the current agent
room, then the agent will move to another room where the drinking action can be ac-
complished. However, the deliberative model reasons on a medium-long term, so if the
need in another drive, not being the dominant one, can be satisfied in the current room,
the plan will prefer to reduce it now, even if the dominant drive increases a bit. Most
previous work on emotional agents would mimic the reactive model, while our model
is able to take into account future recompenses in an integrated way with other agents
