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