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