Perhaps you should try some spelling variations:
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
evolutionary algorithm » evolution algorithm, solution algorithm
near optimisation » _ optimisation, network optimization
modified near » modified seird, modified adam
modified drug » modified df, modified orca

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (( modified near optimisation algorithm ) OR ( modified drug evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified near optimisation algorithm ) or ( modified drug evolutionary algorithm ))*.
