Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
policy optimisation » 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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((same optimization) OR (game optimization)) algorithms ) OR ( policy optimisation algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( ((same optimization) OR (game optimization)) algorithms ) OR ( policy optimisation algorithm ))*.
