Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
cover optimization » qoe optimization, game optimization
core » more, care
parameter » parameters

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

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