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