Perhaps you should try some spelling variations:
"modified objective solution algorithmssss" » "modified objective solution algorithm", "modified objective evolutionary algorithmssss", "modified objective allocation algorithmssss"
"machine learning convolution algorithm" » "machine learning convolution algorithms", "machine learning evolution algorithm", "machine learning solution 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 solution algorithmssss") OR ("machine learning convolution algorithm"))~.
• Removing quotes may allow a broader search: (( modified objective solution algorithmssss ) or ( machine learning convolution algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified objective solution algorithmssss") or ("machine learning convolution algorithm"))*.
