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