Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
optimizer algorithms » optimized algorithms
optimized algorithm » optimized algorithms
market optimization » game optimization, parameter optimization, market capitalization
same » some

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

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