Perhaps you should try some spelling variations:
"certified network optimization algorithms" » "certified network optimisation algorithm", "certified network estimation algorithms", "certified network estimation algorithm", "verified network optimization algorithms"
"modified adaptive ventilation algorithm" » "modified adaptive estimation algorithm", "modified adaptive estimation algorithms", "modified adaptive evolution algorithm", "modified adaptive quantization algorithm", "modified invasive ventilation algorithm", "modified passive 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 adaptive ventilation algorithm") or ("certified network optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive ventilation algorithm") OR ("certified network optimization algorithms"))*.
• Removing quotes may allow a broader search: (( modified adaptive ventilation algorithm ) or ( certified network optimization algorithms ))*.
