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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( ((game optimization) OR (qoe optimization)) algorithm ) or ( parameter optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((game optimization) OR (qoe optimization)) algorithm ) OR ( parameter optimisation algorithm )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((game optimization) OR (qoe optimization)) algorithm ) or ( parameter optimisation algorithm ))".
• Adding a wildcard symbol may retrieve word variants: (( ((game optimization) OR (qoe optimization)) algorithm ) or ( parameter optimisation algorithm ))*.
