Perhaps you should try some spelling variations:
"designed network approximation algorithm" » "designed network approximation algorithms", "defined network approximation algorithm"
"modified adaptive quantization algorithms" » "modified adaptive estimation algorithms", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithms", "modified passive quantization algorithms"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("designed network approximation algorithm") or ("modified adaptive quantization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("designed network approximation algorithm") OR ("modified adaptive quantization algorithms"))*.
• Removing quotes may allow a broader search: (( designed network approximation algorithm ) or ( modified adaptive quantization algorithms ))*.
