Perhaps you should try some spelling variations:
objective optimisation » objective optimization, multiobjective optimization
optimisation algorithm » optimization algorithms, estimation algorithm, estimation algorithms
modified charging » modified caging, modified carbon
station algorithm » estimation algorithm, solution algorithm, estimation algorithms

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