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