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 estimation algorithm" » "modified learning emotion algorithm", "modified lighting estimation algorithm", "mobile learning estimation algorithm", "modified caging estimation algorithm"

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

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified learning estimation algorithm\") OR (\"modified adaptive quantization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified learning estimation algorithm ) OR ( modified adaptive quantization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified learning estimation algorithm") OR ("modified adaptive quantization algorithms"))*.
