Intelligent Systems And Their Societies

Summary of Processes within the General Learner

The General Learner (GL) is an IS (Intelligent System) having the user as it's environment. The user types words or (with the mouse) draws, moves and erases on the screeen; and the program captures this action and responds to it. Also the user can express his approval by pressing the up arrow key and his disapproval with the down arrow.

The Main Process
The main process of GL (called the main function in the C programming language) is as follows:

Main

Do start up

Read memory

While (no "exit" received) do:

MainEvent (getting menu, keyboard and screen inputs from the user)

if (got "exit")

do so

Senses (gets sense inputs)

Brain

DoAction (applies chosen actions)

WorldMgr (moves objects on screen due to elapsed time and computer action)

End of while

if (requested)

Save memory

End

The Brain Process
The Brain functions as follows:

Brain

if (needed)

Forget (rules and concepts not used for the longest time)

if (needed)

Sleep (create more generally applicable response rules)

Make Present Situation (creates concepts and present situation from sense inputs)

if (approval received)

Handle Approval (affects values of concepts in the situation part of the response rule)

if (Previous Situation not equal to Present Situation)

Learn Response Rule (learn rule from activity of person)

else

Make Previous Situation

Make List of Applicable Response Rules (applicable to present situation)

rule = Choose a Response Rule (from memory)

if (rule exists)

Apply Patterns (to rule, adjusts rule)

if (rule is none)

Give Notice: "I don't know what to do"

if (rule exists)

Decompose Action Part of Rule into Concrete Actions
