Re: [Cilib-users] binary PSO

[Gary P. <gpa...@gm...>]

Hi,

The BinaryPSO is nothing more than a normal PSO which has it's position
update equation changed and has been defined to use the binary problem
space.

For example, an extract of a BinaryPSO xml file would be something like:

<algorithms>
      <algorithm id="binaryPSO" class="pso.PSO">
        <initialisationStrategy
class="algorithm.initialisation.ClonedPopulationInitialisationStrategy">
          <entityType class="pso.particle.StandardParticle">
            <positionUpdateStrategy
class="pso.positionupdatestrategies.BinaryPositionUpdateStrategy">
            <sigmoid class="functions.activation.Sigmoid"/>
          </positionUpdateStrategy>
          </entityType>
          <entityNumber>30</entityNumber>
        </initialisationStrategy>
        <topology class="entity.topologies.VonNeumannTopology" />
        <addStoppingCondition
class="stoppingcondition.MaximumIterations" maximumIterations="10000" />
      </algorithm>
    </algorithms>

<problems>
      <problem id="spherical" class="problem.FunctionMinimisationProblem">
        <function class="functions.discrete.BinaryAdapter" domain="B^20"
bitsPerDimension="10" precision="2">
        <function class="functions.continuous.Spherical"
domain="R(-5.12,5.12)^2"/>
      </function>
      </problem>
</problems>

Hope this helps,
Gary
