Table 1 Comparison of GA and PSO as search algorithms
From: An evolutionary feature synthesis approach for content-based audio retrieval
Property | GA | PSO |
|---|---|---|
Genetic operators | Included | Excluded |
Key functions | Crossover | Social particle interaction |
Mutation | Particle velocity updates | |
Information source | All the chromosomes (the whole population moves in one group) | The global best particle (evolution only looks for the best solution) |
Update occurrence | Probabilistic (cross-over and mutation rates) | All particles are updated after each iteration |
Local optimum | Can become easily trapped | Can avoid well the local optima |
