Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
near optimisation » _ optimisation, network optimization
method algorithm » mom algorithm
modified near » modified seird, modified adam
using method » nursing methods, focusing method, using metal

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 method algorithm ) or ( modified near optimisation algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( (code OR core) using method algorithm ) OR ( modified near optimisation algorithm ))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( (code OR core) using method algorithm ) or ( modified near optimisation algorithm ))*".
