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 evolution algorithm" » "modified charging solution algorithm", "modified charging evolutionary algorithm", "modified charging convolution algorithms", "modified caging evolution algorithm", "modified carbon evolution 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 algorithms") OR ("modified charging evolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified notion estimation algorithms ) or ( modified charging evolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion estimation algorithms") or ("modified charging evolution algorithm"))*.
