local optimum

And, in FNN weight training, improved PSO in the convergence rate and the ability to jump out to local optimum algorithm is better than BP.

The particle swarm optimization algorithm which has slow convergence rate and was easily trapping in local optimum was improved.

The results of the experiment showed that the hybrid algorithm has good effect to the function which has many local optimum solutions.

BP neural network, as its nature of gradient descent method, is easy to fall into local optimum.

As a new optimization technique, chaos bears randomicity, ergodicity and the superiority of escaping from a local optimum.

This algorithm can obtain the global optimum, not the local optimum. And it may induce the iteration times enormously.

Absrtact: Basic ant colony algorithm has strong robustness, but has slow convergence and easily be trapped in a local optimum.

It improves and designs crossover operation and mutation operation for avoiding the local optimum.

Local optimum is not even an indication for the global optima .

Simulated annealing was combined to prevent genetic algorithms from local optimum.

However, the standard Particle Swarm Optimization is easy to fall into local optimum, and slow convergence.

When we have large portfolios the problem is computationally too complex and the algorithm used may give only a local optimum.

Standard particle swarm algorithm is easy to fall into local optimum.

In order to quickly obtain the global optimum and local optimum, a hybrid hyper-mutation operator was adopted.
