Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
estimation algorithmss » estimation algorithms, estimation algorithm, optimization algorithms
notion estimation » motion estimation
qoe optimization » game optimization, _ optimization, stage 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 notion estimation algorithmss ) OR ( modified qoe optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified notion estimation algorithmss ) or ( modified qoe optimization algorithm ))*.
