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