Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimization algorithm » optimisation algorithm, estimation algorithm, estimation algorithms
market optimization » game optimization, market capitalization
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: (( parameter optimization algorithms ) or ( market optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( parameter optimization algorithms ) OR ( market optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( parameter optimization algorithms ) or ( market optimization algorithm ))*.
