Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified objective allocation algorithmsss" » "modified objective location algorithmsss", "modified objective allocation algorithms", "modified objective allocation algorithmic"

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

• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified passive quantization algorithm") OR ("modified objective allocation algorithmsss"))~.
• Removing quotes may allow a broader search: (( modified passive quantization algorithm ) or ( modified objective allocation algorithmsss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive quantization algorithm") or ("modified objective allocation algorithmsss"))*.
