Perhaps you should try some spelling variations:
estimation algorithms » estimation algorithm, optimization algorithms, optimisation algorithm
post optimisation » robust optimization, _ optimisation
qoe optimization » game optimization, _ optimization, stage optimization
jose estimation » pose estimation, risk 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: "\"((\\"((post optimisation) OR (qoe optimization)) algorithm\\") or (\\"jose estimation algorithms\\"))\"".
• Removing quotes may allow a broader search: (( ((post optimisation) OR (qoe optimization)) algorithm ) or ( jose estimation algorithms )).
