Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified write estimation algorithms" » "modified write estimation algorithm", "modified write optimization algorithms", "modified write optimisation algorithm", "modified risk estimation algorithms", "modified pose estimation algorithms"

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 write estimation algorithms"))~.
• Removing quotes may allow a broader search: (( modified passive quantization algorithm ) or ( modified write estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified passive quantization algorithm") or ("modified write estimation algorithms"))*.
