Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
method algorithm » mom algorithm
qoe optimization » game optimization, _ optimization, stage optimization
focusing method » forecasting method
code focusing » code using
modified qoe » modified male, modified _, modified bi1

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( code focusing method algorithm ) OR ( modified qoe optimization algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( code focusing method algorithm ) OR ( modified qoe optimization algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( code focusing method algorithm ) OR ( modified qoe optimization algorithms ))*.
