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 allocation optimization algorithm" » "modified allocation optimisation algorithm", "modified allocation estimation algorithm", "modified allocation estimation algorithms", "modified location optimization algorithm"

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 allocation optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified charging optimization algorithms\") OR (\"modified allocation optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified charging optimization algorithms ) OR ( modified allocation optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified charging optimization algorithms") OR ("modified allocation optimization algorithm"))*.
