Perhaps you should try some spelling variations:
optimization algorithm » optimization algorithms, optimisation algorithm, estimation algorithm
near optimization » network optimization, stage optimization, _ optimization
search algorithm » source algorithm
modified near » modified seird, modified adam
using search » using egarch, nursing research, using servo

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

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