Perhaps you should try some spelling variations:
"modified adaptive quantization algorithm" » "modified adaptive estimation algorithm", "modified adaptive ventilation algorithm", "modified passive quantization algorithm"
"modified orca optimisation algorithm" » "modified orca optimization algorithms", "modified orca estimation algorithm", "modified orca estimation algorithms", "modified _ optimisation 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 adaptive quantization algorithm\") OR (\"modified orca optimisation algorithm\"))~".
• Removing quotes may allow a broader search: (( modified adaptive quantization algorithm ) OR ( modified orca optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive quantization algorithm") OR ("modified orca optimisation algorithm"))*.
