Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
notion optimization » network optimization, policy optimization, allocation optimization
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 notion optimization algorithms ) OR ( modified qoe optimization algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified notion optimization algorithms ) OR ( modified qoe optimization algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( modified notion optimization algorithms ) OR ( modified qoe optimization algorithm ))*.
