Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm
estimations algorithm » estimation algorithm
estimation algorithms » estimation algorithm, optimization algorithms, approximation algorithms
dose optimisation » qoe optimization, _ optimisation, game optimization

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

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