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 objective solution algorithms" » "modified objective solution algorithm", "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective evolutionary algorithms", "modified objective allocation algorithms"

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