Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimizer algorithms » optimized algorithms, optimization algorithms
optimized algorithm » optimized algorithms
same optimisation » game optimization, stage optimization, _ optimisation

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( risk ((optimized algorithm) OR (optimizer algorithms)) ) or ( same optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( risk ((optimized algorithm) OR (optimizer algorithms)) ) OR ( same optimisation algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( risk ((optimized algorithm) OR (optimizer algorithms)) ) or ( same optimisation algorithm ))*".
