Perhaps you should try some spelling variations:
"modified passive quantization algorithm" » "modified passive estimation algorithm", "modified adaptive quantization algorithm"
"modified changing optimized algorithms" » "modified changing optimized algorithm", "modified changing optimizer algorithms", "modified changing optimization algorithms", "modified choosing optimizer algorithms", "modified caging optimized 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 changing optimized algorithms") or ("modified passive quantization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified changing optimized algorithms") OR ("modified passive quantization algorithm")).
• Removing quotes may allow a broader search: (( modified changing optimized algorithms ) or ( modified passive quantization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified changing optimized algorithms") or ("modified passive quantization algorithm"))*.
