Inverse Optimisation and Planning
for brachytherapy has to
consider several
Objectives
and is thus a
Multiobjective
(
MO
) problem.
We have
competing Objectives
. Increasing the dose in the
Target will increase the dose outside it.
A trade-off between the Objectives exist and we never have a
situation in which all the Objectives can be in the best
possible way satisfied simultaneously.
