Perhaps you should try some spelling variations:
optimization algorithms » estimation algorithms, estimation algorithm, optimized algorithms
optimisation algorithm » estimation algorithm, estimation algorithms
game optimization » stage optimization, qoe optimization, market optimization
qoe optimisation » qoe optimization, _ optimisation, _ optimization
modified game » modified male, modified adam
modified qoe » modified male, modified _, modified bi1

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified qoe optimisation algorithm ) OR ( modified game optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified qoe optimisation algorithm ) or ( modified game optimization algorithms ))*.
