Perhaps you should try some spelling variations:
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation algorithm"
"modified aging solution algorithm" » "modified aging evolution algorithm", "modified aging convolution algorithms", "modified aging evolutionary algorithm", "modified caging solution algorithm", "modified saline solution 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 adaptive estimation algorithm") OR ("modified aging solution algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive estimation algorithm\") OR (\"modified aging solution algorithm\"))".
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithm ) OR ( modified aging solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithm") OR ("modified aging solution algorithm"))*.
