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