Perhaps you should try some spelling variations:
"modified adaptive estimation algorithmss" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive optimization algorithms", "modified adaptive ventilation algorithmss", "modified quantile estimation algorithmss", "modified adaptive quantization algorithmss", "modified passive estimation algorithmss"
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective estimation algorithms"

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