Perhaps you should try some spelling variations:
"modified notion estimation algorithms" » "modified notion estimation algorithm", "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified motion estimation algorithms"
"modified charging optimizer algorithms" » "modified charging optimized algorithms", "modified charging optimized algorithm", "modified charging optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimizer algorithms", "modified carbon optimizer 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 optimizer algorithms") OR ("modified notion estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified charging optimizer algorithms ) or ( modified notion estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified charging optimizer algorithms") or ("modified notion estimation algorithms"))*.
