Perhaps you should try some spelling variations:
optimization algorithms » optimisation algorithm, estimation algorithms, estimation algorithm
evolutionary algorithm » evolution algorithm, solution algorithm
near optimization » network optimization, stage optimization, _ 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 optimization algorithms ) OR ( modified drug evolutionary algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified near optimization algorithms ) or ( modified drug evolutionary algorithm ))*.
