Abstract :
Optimization of noisy non-linear problems plays a key role in
engineering and design problems. These optimization problems can't
be solved effectively by using conventional optimization methods.
However, metaheuristic algorithms such as Genetic Algorithm (GA)
and Particle Swarm Optimization (PSO) seem very efficient to
approach in these problems and became very popular. The efficiency
of these methods against many new metaheuristic optimization algorithms
has been proved in previous works, however a robust comparison
between GA and PSO to solve noisy nonlinear problems has not
been reported yet. Therefore, in this paper GA and PSO are adapted
to find optimal solutions of some noisy mathematical models. Based
on the obtained results, GA shows a promising potential in terms of
number of iteration to converge and solutions found so far for either
for optimization of low or elevated levels of noise.
