Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
cover optimisation » qoe optimization
pose optimization » qoe optimization, response optimization, policy 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: (( cover optimisation algorithm ) OR ( ((pose optimization) OR (game optimization)) algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( cover optimisation algorithm ) or ( ((pose optimization) OR (game optimization)) algorithms ))~".
• Adding a wildcard symbol may retrieve word variants: (( cover optimisation algorithm ) or ( ((pose optimization) OR (game optimization)) algorithms ))*.
