Perhaps you should try some spelling variations:
"machine learning solution algorithm" » "machine learning evolution algorithm", "machine learning convolution algorithms", "machine learning evolutionary algorithm", "machine learning convolution algorithm", "machine learning emotion algorithm"
"modified objective allocation algorithmss" » "modified objective location algorithmss", "modified objective allocation algorithms", "modified objective allocation algorithmic"

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: (("machine learning solution algorithm") OR ("modified objective allocation algorithmss"))~.
• Removing quotes may allow a broader search: (( machine learning solution algorithm ) or ( modified objective allocation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("machine learning solution algorithm") or ("modified objective allocation algorithmss"))*.
