Abstract:
Emergence of cities is a basis for city planning. Scientists in the field of spatial
economics have proposed several theories on how cities are emerged. These theories
have been transformed into different algorithms to determine final emergences. For a
given emergent algorithm, optimal emergences cannot be predetermined by means of
mathematical equations. Therefore, determining optimal emergences is an NP-Class
(Nondeterministic-Polynomial Class) problem. At present, simulation is one of the
approaches to study the behaviors and characteristics of the emergence. There had
been an attempt to determine optimal or favourable emergences by implementing a
simulation system which applied a technique in Soft Computing known as Genetic
Algorithm. Nevertheless, improvement can still be made in order to produce more
efficient emergences. This research is concerned with the improvement of the genetic
algorithm system by incorporating a heuristic approach, which is based on the selfsufficiency
concept. The improved system is able to determine two possible types of
more efficient emergences. This study also determined suitable parametric values for
the two genetic operators, the crossover rate and the mutation rate, which can be used
in future studies in this application.
