Perhaps you should try some spelling variations:
"modified qoe optimization algorithm" » "modified qoe optimization algorithms", "modified qoe optimisation algorithm", "modified qoe estimation algorithm", "modified game optimization algorithm", "modified _ optimization algorithm", "modified stage optimization algorithm", "modified male optimization algorithm", "modified bi1 optimization algorithm"
"modified invasive ventilation algorithm" » "modified invasive estimation algorithm", "modified invasive estimation algorithms", "modified invasive evolution algorithm", "modified adaptive ventilation algorithm", "modified passive ventilation 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 invasive ventilation algorithm") OR ("modified qoe optimization algorithm"))~.
• Removing quotes may allow a broader search: (( modified invasive ventilation algorithm ) or ( modified qoe optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified invasive ventilation algorithm") or ("modified qoe optimization algorithm"))*.
