---|---|---|---|
Swarm size | 30 | 30 | 30 |
Number of iterations | 50–80 | 50–80 | 50–80 |
Acceleration Constants | C1 = 1.25, C2 = 2.25, C3 = 2.25 | C1 = 1.25, C2 = 2.25, C3 = 0 | C1 = 1.25, C2 = 0, C3 = 2.25 |
Communication topology | Ring | Fully connected | Ring |
Inertia weight | Linearly decreasing (0.4 − 0.2) |
Linearly decreasing (0.4 − 0.2) |
Linearly decreasing (0.4 − 0.2) |
Number of used threads | Depends on the objective function | Depends on the number of sub-spaces | Depends on the number of created neighborhoods |
Stopping criteria | - The maximum number of iterations - The maximum number of iterations without improvement of Gbest |
- The maximum number of iterations - The maximum number of iterations without improvement of Gbest |
-A precision relative to the radius - A precision relative to the distance of Gbest - The maximum number of iterations without improvement of Gbest |
Current usage metrics show cumulative count of Article Views (full-text article views including HTML views, PDF and ePub downloads, according to the available data) and Abstracts Views on Vision4Press platform.
Data correspond to usage on the plateform after 2015. The current usage metrics is available 48-96 hours after online publication and is updated daily on week days.
Initial download of the metrics may take a while.
