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