Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimizer algorithms » optimized algorithms, optimized algorithm
qoe optimization » game optimization, _ optimization, stage optimization
write optimizer » write optimized

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 ( write optimizer algorithms ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( qoe optimization algorithms ) OR ( write optimizer algorithms ))*.
