Class GlobalTopology

Namespace

NanoQL.Experimental

Assembly

NanoQL.dll

The global topology: each particle's social best is the best of all the particles' personal bests: QuantLib's GlobalTopology.

[Experimental("NQL0001")]
public sealed class GlobalTopology : ParticleSwarmOptimizationTopology

Remarks

The best is the smallest personal best, and every particle's social best is set to it, the best particle's own included: QuantLib's keeps the largest (if (bestF < pBF_[i])), steering every particle toward the worst, and skips the best particle, leaving its social best at the zero vector it started with; on a shifted sphere it stops at 6.4e-5 where the k-neighbours topology reaches 2.7e-18 (its standard QuantLib's own definition above the class; Divergences/ParticleSwarmTopologyTests.cs).

Methods

Clone()

A copy for a minimization, unbound, its generators at their seeds.

public override ParticleSwarmOptimizationTopology Clone()

Returns

ParticleSwarmOptimizationTopology

The copy.

FindSocialBest()

Sets each particle's social best for the iteration (QuantLib's findSocialBest).

public override void FindSocialBest()

SetSize(int)

Initializes the state for the problem (QuantLib's setSize).

public override void SetSize(int M)

Parameters

M int

The swarm's size.
