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

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