Example GB01 : cross-section biasing
This example illustrates how to bias process cross-sections.
Generally speaking, the scheme consists of a G4VBiasingOperator that takes decisions on what sort of biasing is to be applied. The operator makes these decision on requests of the G4BiasingProcessInterface process. This process wraps an actual physics process and asks to the operator about what sort of biasing it should apply. This operator selects G4VBiasingOperation objects that implement the actual biasing content.

Example GB02 : force collision biasing
This example illustrates how to make a force collision biasing in a way that is essentially the same than the MCNP one.

Example GB03 : geometry based biasing
This example illustrates a use of generic biasing classes to implement a technique near to "geometry importance biasing".
The geometry is the same than in EM tests, with the sampling calorimeter made of a series of layers of absorber and gap.
The biasing applies to neutrons only.

Example GB04 : bremsstrahlung splitting
This example illustrates the use of the generic biasing classes to create a bremsstrahlung splitting technique. Note that the EM package also offers a bremsstrahlung splitting, that is built-in to the package.

Example GB05: splitting by cross-section
This example illustrates a technique that uses physics cross-sections to determine the splitting [killing] rate in a shielding problem. This technique is supposed to be an invention, and this example here is not optimized. The technique is applied here to neutrons.

Example GB06: parallel geometries with generic biasing
This example demonstrates the use of parallel geometries in generic biasing, on a classical shield problem, using geometry-based importance biasing.

Example GB07 : leading particle biasing
This example illustrates how to use the leading particle biasing option.
It uses the G4BOptnLeadingParticle biasing operation located in:

and defines the following biasing operation to handle it:
