Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
simulation algorithms » estimation algorithms, estimation algorithm, solution algorithm
qoe optimization » game optimization, _ optimization, stage optimization
via simulation » a simulation, _ simulation, 3d simulation

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

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