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 solution algorithmssss" » "modified objective evolution algorithmssss", "modified objective convolution algorithmsssss", "modified objective evolutionary algorithmssss", "modified objective allocation algorithmssss"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machine learning solution algorithm") OR ("modified objective solution algorithmssss"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"machine learning solution algorithm\") OR (\"modified objective solution algorithmssss\"))".
• Removing quotes may allow a broader search: (( machine learning solution algorithm ) OR ( modified objective solution algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("machine learning solution algorithm") OR ("modified objective solution algorithmssss"))*.
