Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
policy optimization » topology optimization
same optimization » stage optimization, qoe optimization, market 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: (( ((same optimization) OR (game optimization)) algorithms ) OR ( policy optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( ((same optimization) or (game optimization)) algorithms ) or ( policy optimization algorithm ))*.
