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