Perhaps you should try some spelling variations:
"modified adaptive quantization algorithmssss" » "modified adaptive ventilation algorithmssss", "modified passive quantization algorithmssss"
"modified objective allocation algorithms" » "modified objective estimation algorithms", "modified objective approximation algorithms"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive quantization algorithmssss\") OR (\"modified objective allocation algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithmssss ) OR ( modified objective allocation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithmssss") OR ("modified objective allocation algorithms"))*.
