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"
"mobile learning methods algorithm" » "mobile nursing methods algorithm", "machine learning methods algorithm"

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

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