Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
game optimization » stage optimization, qoe optimization, market optimization
method algorithm » mom algorithm
modified game » modified male, modified adam
core using » care nursing

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( ((core using) OR (code using)) method algorithm ) or ( modified game optimization algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( ((core using) OR (code using)) method algorithm ) OR ( modified game optimization algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( ((core using) OR (code using)) method algorithm ) or ( modified game optimization algorithm ))*".
