Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimizer algorithms » optimized algorithms, optimization algorithms
optimized algorithm » optimized algorithms
cover optimisation » qoe optimization
done » dong, one, don

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

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