What is fuzzy logic?
Fuzzy logic is basically a way to program machines so they look at the world in a more human
way, with degrees of truth. Instead of cold, hard parameters and strict data sets, fuzzy logic
assumes a more practical approach. Using numbers, it incorporates non
definitive words like
"slightly" or "almost" into its decision
making processes. Check onl

Try both manual and fuzzy control of getting the load from the ship to the dock. These controls
can be selected by clicking on the buttons underneath the simulation of the ship and dock.

decrease the power
lift the load
lower the load
lock the load
Explain which method causes the least sway (movement forwards and backwards) at the
fastest speed of the box being loaded/unloaded from the ship. (2 marks)

Computers and common sense logic
One of the fundamental problems encountered in AI has become known as the commonsense
knowledge problem. While researchers were aware that in an AI system, knowledge would h
to be explicitly represented, they did not anticipate the vast amount of implicit knowledge we all
share about the world and ourselves.
Designers of AI systems did not consider producing rules like "If President Clinton is in
Washington, then his left
foot is also in Washington," or
"If a father has a son, then the son is younger than the father and remains younger for his entire
life." This is implicit knowledge and we never stop to state this explicitly.
It is plain to see that commonsense knowledge
represents an enormous hurdle for the
development of general purpose intelligent systems. It is clear that not all human knowledge is
represented in such an explicit or declarative form. Imagine writing everything we know
formulated as a series of if
One of the most important aspects of commonsense knowledge is that it is gained through
experience. If computers were to develop commonsense knowledge, then this would have huge
implications for storage requirements.
