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 static optimization algorithm" » "modified static optimisation algorithm", "modified static estimation algorithm", "modified static estimation algorithms", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization algorithm"

Try widening your search to All Fields.

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