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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("dose estimation algorithm") or ((("_ optimisation algorithm") OR ("_ optimization algorithm"))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("dose estimation algorithm") OR ((("_ optimisation algorithm") OR ("_ optimization algorithm")))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"dose estimation algorithm\") or (((\"_ optimisation algorithm\") OR (\"_ optimization algorithm\"))))".
• Removing quotes may allow a broader search: (( dose estimation algorithm ) or ((( _ optimisation algorithm ) OR ( _ optimization algorithm )))).
• Adding a wildcard symbol may retrieve word variants: (("dose estimation algorithm") or ((("_ optimisation algorithm") OR ("_ optimization algorithm"))))*.
