Topics

The list of topics includes, but is not limited to:

combinatorial optimization
global optimization
multiobjective optimization
optimization in dynamic and/or noisy environments
large scale optimization
parallel and distributed approaches in optimization
random search algorithms,
simulated annealing,
tabu search
other derivative free optimization methods
nature inspired optimization methods (evolutionary algorithms, ant
colony optimization, particle swarm optimization, immune artificial
systems etc)
hybrid optimization algorithms involving natural computing
techniques and other global and local optimization methods
optimization methods for learning processes and data mining
computational optimization methods in statistics, econometrics,
finance, physics, medicine, biology, engineering etc


Proceedings
