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

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"((game optimisation) OR (game optimization)) algorithm\\") or (\\"qoe estimation algorithms\\"))\"".
• Removing quotes may allow a broader search: (( ((game optimisation) OR (game optimization)) algorithm ) or ( qoe estimation algorithms )).
