Uncertainty Is A Real World Problem Uncertainty can powerfully
assist Expert Systems to diagnose problems by ignoring the “If,
then..” routine and by following an elimination algorithm. This
website suggests that intuition of the human mind follows such a
routine. From its early beginnings, the Artificial Intelligence
community sought to understand human intelligence by building
computer programs, which exhibit intelligent behavior. AI
researchers assume rightly that intelligence is essentially a
problem solving ability. But, they make the mistake of assuming
that such problems have clear logical, or mathematical
solutions. Unfortunately for them, problems in the real world do
not present clear cut answers. The diagnosis of a disease does
not follow simple logical paths; nor can it be calculated. If a
patient has a group of symptoms, then she has a particular
disease. But many of these symptoms are shared by other
diseases. Occasionally, some of these symptoms may also be
absent for the disease. The real worl
