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 adam predation algorithm" » "modified adam predators algorithm", "modified adam estimation algorithm", "modified df predation algorithm", "modified near predation algorithm"

Try widening your search to All Fields.

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 adam predation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive estimation algorithms") OR ("modified adam predation algorithm")).
• Removing quotes may allow a broader search: (( modified adaptive estimation algorithms ) or ( modified adam predation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive estimation algorithms") or ("modified adam predation algorithm"))*.
