Purpose

Handles optimization of dose with respect to particle numbers.

Parameters

iter()
Maximum number of iterations. Remembered. Startup default is 5.
bio
Optimize using biological dose. Remembered.
phys
Optimize using physical dose. Remembered.
simultaneous
Simultaneous optimization of multiple fields. Not yet implemented.
singly
Separate optimization of multiple fields.
matchonly
Optimize using only a simple peak-to-dose matching algorithm. Otherwise a conjugate gradient method is used to equilibrate peaks and valleys.
lateral
Include lateral correlations between raster positions. Not yet implemented.
events(nevt)
Not yet implemented.
eps(eps)
Minimum relative change of chi-square. If the actual change is below, the iteration is aborted. Startup default is 1E-3.
doseweightfactor(dwf)
The prescribed dose is multiplied with this factor to yield sort of an experimental error, which enters as a weight in the chi-square evaluation. Startup default is 2.5E-2.
field(idlist)
List of field id's to be optimized.
debug
Debug switch. Lots of output !

Remark

none

Examples

opt / field(*) bio
Optimize all defined fields using the biologically effective dose.
