List<Guid> guids = new List<Guid>();

foreach (IGH_Param param in Component.Params.Input)

{

  foreach (IGH_Param source in param.Sources)

  { 

    guids.Add(source.InstanceGuid);

  }

}

Im trying to Implement Particle Swarm Optimisation  in Grasshopper which requires

manipulation of sliders or Gene Pool component to evaluate fitness...

Changing a slider during a solution is not allowed. Or it's at least a very bad idea, I'll make sure it's not allowed in GH2, just to avoid confusion.

Galapagos sets sliders first and then triggers a new solution. However your RunScript code runs within a solution, so you're going to have to find a way to delay your slider-adjusting-logic. It's a very similar problem to this discussion: http://www.grasshopper3d.com/forum/topics/failed-to-collect-data?pa...
