Perhaps you should try some spelling variations:
"modified notion optimization algorithmssss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified network optimization algorithmssss", "modified policy optimization algorithmssss", "modified allocation optimization algorithmssss"
"modified adaptive estimation algorithm" » "modified adaptive ventilation algorithm", "modified quantile estimation algorithm", "modified adaptive quantization algorithm", "modified passive estimation algorithm"

You may be able to get more results by adjusting your search query.

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