Evolutionary computation, offers practical advantages to the
researcher facing difficult optimization problems. These
advantages
are multifold, including the simplicity of the approach, its
robust
response to changing circumstance, its flexibility, and many
other
facets. Many real-world search and optimization problems from
sciences
and engineering are naturally posed as mathematical
programming
problems involving multiple objectives. Due to the lack of
suitable
techniques for finding multiple optimal solutions by classical
means,
such problems are artificially converted into a
single-objective
optimization problem
and solved. Unfortunately, the outcome of such methods is
quite
dependent on the adopted conversion procedure.
Recently, evolutionary algorithms are proposed to solve these
problems
in a less-subjective and efficient manner. Instead of finding
one
solution at a time, evolutionary multiobjective optimization
methods
find a number of Pareto-optimal solutions in one simulation
and leave
the decision-making task for later.
In this tutorial, we introduce the fundamental concepts of
evolutionary algorithms and the basics of multi-objective
optimization
with a quick review of the state-of-the-art techniques
practiced in
this emerging field. Some research pointers and some
potential
application domains of EMO will also be highlighted in this
tutorial.
