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 df predation algorithm" » "modified df predators algorithm", "modified df estimation algorithm", "modified _ predation algorithm", "modified adam predation algorithm", "modified bi1 predation 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 algorithms") OR ("modified df predation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive estimation algorithms\") OR (\"modified df predation algorithm\"))".
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithms ) OR ( modified df predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithms") OR ("modified df predation algorithm"))*.
