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