Perhaps you should try some spelling variations:
"_ optimisation algorithm" » "_ optimization algorithms", "_ estimation algorithm", "_ optimization algorithm"
"dose estimation algorithms" » "dose estimation algorithm", "dose optimization algorithms", "dose approximation algorithms", "pose estimation algorithms", "risk estimation algorithms", "cover estimations algorithms"
"_ optimized algorithms" » "_ optimized algorithm", "_ optimizer algorithms", "_ optimization algorithms"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"dose estimation algorithms\") OR (((\"_ optimisation algorithm\") OR (\"_ optimized algorithms\"))))~".
• Removing quotes may allow a broader search: (( dose estimation algorithms ) OR ((( _ optimisation algorithm ) OR ( _ optimized algorithms ))))~.
• Adding a wildcard symbol may retrieve word variants: (("dose estimation algorithms") OR ((("_ optimisation algorithm") OR ("_ optimized algorithms"))))*.
