Perhaps you should try some spelling variations:
"modified adaptive quantization algorithmss" » "modified adaptive estimation algorithms", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithmss", "modified passive quantization algorithmss"
"modified objective approximation algorithm" » "modified objective approximation 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 adaptive quantization algorithmss") OR ("modified objective approximation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive quantization algorithmss\") OR (\"modified objective approximation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithmss ) OR ( modified objective approximation algorithm ))*.
