Perhaps you should try some spelling variations:
"modified learning convolution algorithms" » "modified learning evolution algorithm", "modified learning solution algorithm", "mobile learning convolution algorithms", "modified caging convolution algorithms"
"modified adaptive ventilation algorithms" » "modified adaptive estimation algorithms", "modified adaptive estimation algorithm", "modified adaptive quantization algorithms", "modified invasive ventilation algorithms", "modified passive ventilation algorithms"

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 algorithms") or ("modified learning convolution algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified adaptive ventilation algorithms") OR ("modified learning convolution algorithms")).
• Removing quotes may allow a broader search: (( modified adaptive ventilation algorithms ) or ( modified learning convolution algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive ventilation algorithms") or ("modified learning convolution algorithms"))*.
