Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
allocation optimized » allocation optimization
optimized algorithm » optimized algorithms, optimizer algorithms
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.

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