Abstract

According to the actual requirements we have to prepare 4 different
types of behavior functions

1 Problem to be Solved

In part 2 we have mentioned the following 4 types of behavior functions
which we need:
1. The behavior function phi of the actor is ’empty’  phi = 0. The actor
functions like an ’envelope’: you can see the body of the actor on the
screen, but his behavior depends completely from the inputs given by
a human person.

2. The behavior function  of the actor is driven by one, fixed rule  phi(i) = const. The actor will do always the same, independent from the environment.
3. The behavior function  of the actor is driven by a source of random
values; therefore the output is completely random phi(i) = random.
4. The behavior function  of the actor is driven by a source of random
value but simultaneously the actor has some simple memory  remembering the last n steps before finding food. Therefore the behavior
is partially random, partially directed depending from the distance
to the goal food:  phi : I  x IS —> IS  x O with internal states IS as
a simple memory which can collect data from the last n-many steps
before reaching the goal. If the memory  is not empty then it can
happen, that the actual input maps the actual memory-content and
then the memory gives the actor a ’direction’ for the next steps.

In this part 3 we will program the cases 1-3 and we will implement a
food-intake function which will increase the energy level again.
