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