Perhaps you should try some spelling variations:
"modified adaptive estimation algorithmsssss" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive ventilation algorithmsssss", "modified quantile estimation algorithmsssss", "modified adaptive quantization algorithmsssss", "modified passive estimation algorithmsssss"
"modified objective optimization algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective estimation 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 objective optimization algorithm") or ("modified adaptive estimation algorithmsssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified objective optimization algorithm") OR ("modified adaptive estimation algorithmsssss")).
• Removing quotes may allow a broader search: (( modified objective optimization algorithm ) or ( modified adaptive estimation algorithmsssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified objective optimization algorithm") or ("modified adaptive estimation algorithmsssss"))*.
