Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
objective optimized » objective optimal, objective optimization
optimized algorithm » optimized algorithms, optimizer algorithms
qoe optimisation » qoe optimization, _ optimisation, game optimization
modified qoe » modified male, modified _, modified bi1

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified objective optimized algorithm ) or ( modified qoe optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified objective optimized algorithm ) OR ( modified qoe optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimized algorithm ) or ( modified qoe optimisation algorithm ))*.
