| 20 | November 9th, 2007 A.Howard geombias-V09-00-01 |
|---|
| 21 | - Revised search algorithm to Weight/UpperBound + 1. |
|---|
| 22 | |
|---|
| 23 | November 9th, 2007 A.Howard geombias-V09-00-00 |
|---|
| 24 | - Modified WeightWindow algorithm according to Thomas Booth's |
|---|
| 25 | recommendation (MCNP author). In order to not introduce extra variance |
|---|
| 26 | in the case of splitting to the survival weight when the weight is |
|---|
| 27 | above the upper weight window - modified G4WeightWindowAlgorithm.cc |
|---|
| 28 | |
|---|
| 29 | June 4th, 2007 A.Howard geombias-V08-03-02 |

|---|
| 32 | |
|---|
| 33 | May 31st, 2007 A.Howard geombias-V08-03-01 |
|---|
| 34 | - Removed classes from old biasing scheme. These are now replaced by |
|---|
| 35 | either CoupledTransportation (parallel navigation) or in |
|---|
| 36 | processe/biasing. In addition the scoring is implemented with the new |
|---|
| 37 | scoring frame-work (digits_hits) and processes/scoring. |
|---|
| 38 | - The following classes are removed: |
|---|
| 39 | G4IStore, G4ParallelNavigator, G4ParallelStepper, G4ParallelWorld, |
|---|
| 40 | G4VCellScorer, G4VCellScorerStore, G4VIStore, G4VParallelStepper, |
|---|
| 41 | G4VPGeoDriver, G4VScorer, G4ImportanceSplitExaminer, |
|---|
| 42 | G4VImportanceSplitExaminer, G4VWeightWindowExaminer, |
|---|
| 43 | G4WeightWindowExaminer |
|---|
| 44 | - Classes are kept in the HEAD for testing purposes. |
|---|
| 45 | |
|---|
| 46 | May 11th, 2007 G.Cosmo geombias-V08-03-00 |
