Particle Swarm Search

The Particle Swarm Search is one of the non-circular search options in Slide for locating critical slip surfaces. The Particle Swarm Search is also known as Particle Swarm Optimization (PSO).

The Particle Swarm Search is a metaheuristic search method in which randomness is introduced in some steps of the algorithm.  

To enable a Particle Swarm Search:

  1. In the Slip Surface Options dialog, set the Search Method = Particle Swarm Search.

  2. Set the Particle Swarm Search Options (Max Iterations and Number of Particles).

The Particle Swarm Search requires no user defined search objects, the algorithm will run automatically when you select Compute.
