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

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

• Performing a fuzzy search may retrieve terms with similar spellings: (( certified network optimisation algorithm ) or ( modified charging station algorithm ))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (( certified network optimisation algorithm ) OR ( modified charging station algorithm )).
• Adding a wildcard symbol may retrieve word variants: (( certified network optimisation algorithm ) or ( modified charging station algorithm ))*.
