Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
same optimization » stage optimization, qoe optimization, market optimization
game optimisation » stage optimization, _ optimisation, qoe optimization
game optimization » stage optimization, qoe optimization, market optimization

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: (( same optimization algorithms ) OR ( ((game optimisation) OR (game optimization)) algorithm ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( same optimization algorithms ) or ( ((game optimisation) OR (game optimization)) algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( same optimization algorithms ) or ( ((game optimisation) OR (game optimization)) algorithm ))*.
