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