Perhaps you should try some spelling variations:
"modified charging estimation algorithms" » "modified charging optimization algorithms", "modified charging optimisation algorithm", "modified charging approximation algorithms", "modified charging station algorithms", "modified caging estimation algorithms", "modified carbon estimation algorithms"
"modified notion estimation algorithm" » "modified motion estimation algorithm"

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 notion estimation algorithm") OR ("modified charging estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified notion estimation algorithm ) or ( modified charging estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithm") or ("modified charging estimation algorithms"))*.
