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

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