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.

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