Perhaps you should try some spelling variations:
"modified adaptive quantization algorithms" » "modified adaptive estimation algorithms", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithms", "modified passive quantization algorithms"
"modified learning convolution algorithm" » "modified learning convolution algorithms", "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithm", "modified caging convolution 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 learning convolution algorithm") OR ("modified adaptive quantization algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning convolution algorithm\") OR (\"modified adaptive quantization algorithms\"))*".
• Removing quotes may allow a broader search: (( modified learning convolution algorithm ) OR ( modified adaptive quantization algorithms ))*.
