Perhaps you should try some spelling variations:
"modified objective optimization algorithms" » "modified objective optimisation algorithm", "modified objective estimation algorithm", "modified objective optimized algorithms", "modified multiobjective optimization algorithms"
"modified charging estimation algorithms" » "modified charging estimation algorithm", "modified charging optimisation algorithm", "modified charging approximation algorithms", "modified charging station algorithms", "modified caging estimation algorithms", "modified carbon 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 estimation algorithms") OR ("modified objective optimization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified charging estimation algorithms\") OR (\"modified objective optimization algorithms\"))".
• Removing quotes may allow a broader search: (( modified charging estimation algorithms ) OR ( modified objective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified charging estimation algorithms") OR ("modified objective optimization algorithms"))*.
