Pandemonium and Problems
Pandemonium Patterns for
Decision-Making, Projection and Problem-Solving
Decision-Making
Pandemonium may be used to choose from a set of options. Each demon
in a set is responsible for one option. A demon watches its input and
evaluates its option. If the result of this evaluation are sufficiently
positive, the demon shrieks. better the option looks, the louder the
shriek. The owner of the set of demons pays attention to the loudest
shriek(s); the owner can pick the option with the loudest demon. This
pattern is particularly useful for deciding "What should I pay attention
to next?". From a software-engineering point of view, a demon can be a
way of encapsulating the way an option is evaluated.
Projection
Pandemonium can be used to project the state of a system into the
future. A set of demons is used to repeatedly make the decision
"What will happen next?" or "What will I do next?". The result of
each decision is used to update the state of (a copy of) the system.
Multiple Emotional Projection
Pandemonium can be used to create a number of possible future states
of a system. A set of demons using
emotions for evaluation, is repeatedly
used to project the state of a system into the future (see
the Projection pattern, above). Between each
projection, the state of the system is reset but the emotions
(belonging to the demons) are not reset. Because the starting
emotional state of the demons can be different in each projection,
the results of each projection can be different. The emotions of
the demons perturb the projections. While the value of the results
of each projection may be low, the value of the distribution of
results of all the projections may be higher.
Problem-Solving
Pandemonium may be used to solve certain types of problems that
required multiple decisions. A set of demons is used to repeatedly
decide "Which decision should I make next?". Each decision to be
made, can be addressed by a set of demons, as described in the
Decision-Making pattern, above.
Multiple Emotional Problem Solving
Pandemonium can be used to find solutions to hard problems -
problems in which the solution-space is too large to search
exhaustively. A set of demons using
emotions for evaluation, is repeatedly
tries to find a solution to a problem (see the
Problem-Solving pattern, above). Between each
try, the state of the system is reset but the emotions (belonging
to the demons) are not reset. Because the starting emotional state
of the demons can be different in each projection, the results of
each projection can be different. The emotions of the demons perturb
the exploration of the solution-space. This is a technique for finding
multiple different solutions to a problem, so that the best may be
kept.
