Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified trace optimized algorithm" » "modified trace optimized algorithms", "modified trace optimizer algorithms", "modified write optimized algorithm", "modified traces optimized algorithm", "modified male optimized algorithm", "modified orca optimized algorithm"

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