Perhaps you should try some spelling variations:
"modified charging optimization algorithms" » "modified charging optimisation algorithm", "modified charging estimation algorithms", "modified charging estimation algorithm", "modified charging optimisation algorithms", "modified charging estimation algorithmss", "modified staffing optimization algorithms", "modified caging optimization algorithms", "modified carbon optimization algorithms"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective estimation algorithms"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified charging optimization algorithms") or ("modified objective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified charging optimization algorithms") OR ("modified objective optimization algorithm")).
• Removing quotes may allow a broader search: (( modified charging optimization algorithms ) or ( modified objective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified charging optimization algorithms") or ("modified objective optimization algorithm"))*.
