Perhaps you should try some spelling variations:
"modified notion optimization algorithmss" » "modified notion optimization algorithms", "modified notion optimisation algorithm", "modified notion estimation algorithm", "modified network optimization algorithmss", "modified policy optimization algorithmss", "modified allocation optimization algorithmss"
"modified invasive estimation algorithms" » "modified invasive estimation algorithm", "modified invasive optimization algorithms", "modified invasive optimisation algorithm", "modified invasive ventilation algorithms", "modified passive estimation algorithms"

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 invasive estimation algorithms") OR ("modified notion optimization algorithmss"))~.
• Removing quotes may allow a broader search: (( modified invasive estimation algorithms ) or ( modified notion optimization algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive estimation algorithms") or ("modified notion optimization algorithmss"))*.
