Perhaps you should try some spelling variations:
"modified rough approximation algorithm" » "modified rough approximation algorithms", "modified rough approximations algorithm", "modified one approximation algorithm"
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified rough approximation algorithm") OR ("modified adaptive quantization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified rough approximation algorithm\") OR (\"modified adaptive quantization algorithm\"))*".
• Removing quotes may allow a broader search: (( modified rough approximation algorithm ) OR ( modified adaptive quantization algorithm ))*.
