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