Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
parameter estimates » parameter estimation
estimates algorithm » estimation algorithm, estimation algorithms
qoe optimization » game optimization, _ optimization, stage optimization
core » more, care

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( (code OR core) qoe optimization algorithm ) or ( modified parameter estimates algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( (code OR core) qoe optimization algorithm ) OR ( modified parameter estimates algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (code OR core) qoe optimization algorithm ) or ( modified parameter estimates algorithm ))*".
