Perhaps you should try some spelling variations:
"modified near convolution algorithms" » "modified near evolution algorithm", "modified near solution algorithm", "modified learning convolution algorithms", "modified seird convolution algorithms", "modified adam convolution algorithms"
"modified objective estimation algorithm" » "modified objective optimization algorithm", "modified objective allocation algorithm"

You may be able to get more results by adjusting your search query.

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