Perhaps you should try some spelling variations:
objective optimization » multiobjective optimization
optimization algorithm » optimization algorithms, estimation algorithm, estimation algorithms
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
near optimisation » _ optimisation, network optimization
modified near » modified seird, modified adam

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 objective optimization algorithm ) OR ( modified near optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (( modified objective optimization algorithm ) or ( modified near optimisation algorithm ))*.
