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

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: "(( some optimization algorithms ) OR ( parameter optimization algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( some optimization algorithms ) OR ( parameter optimization algorithm ))*.
