| Object () | |
The particles to be optimized must have optimizable x,y,z attributes and a non-optimizable "Stokes radius"; this optimizer assumes the score to be energy in kcal/mol, the xyz coordinates to be in angstroms and the diffusion coefficent be in cm^2/s
kernel::Particles without optimized x,y,z and nonoptimized D are skipped.
Rigid bodies are supported.
BrownianDynamics uses a SimulationParameters particle to store the parameters of the simulation. Such a particle must be passed on creation. The BrownianDynamics object will at least see updates to the SimulationParamters particle which occur before the call to BrownianDynamics::optimize() or BrownianDynamics::simulate(), changing the the parameters during optimization has undefined results.
The optimizer can either automatically determine which particles to use from the model or be passed a SingletonContainer for the particles. If such a container is passed, particles added to it during optimization state updates are handled properly.

If sc is not null, that container will be used to find particles to move, otherwise the model will be searched.
