Perhaps you should try some spelling variations:
"modified qoe optimization algorithms" » "modified qoe optimisation algorithm", "modified qoe estimation algorithms", "modified qoe estimation algorithm", "modified game optimization algorithms", "modified _ optimization algorithms", "modified stage optimization algorithms", "modified male optimization algorithms", "modified bi1 optimization algorithms"
"modified passive ventilation algorithm" » "modified passive estimation algorithm", "modified passive estimation algorithms", "modified passive evolution algorithm", "modified adaptive ventilation algorithm", "modified invasive ventilation algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified passive ventilation algorithm") or ("modified qoe optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified passive ventilation algorithm") OR ("modified qoe optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified passive ventilation algorithm ) or ( modified qoe optimization algorithms ))*.
