Perhaps you should try some spelling variations:
"modified learning solution algorithm" » "modified learning evolution algorithm", "modified learning convolution algorithms", "modified learning evolutionary algorithm", "mobile learning solution algorithm", "modified caging solution algorithm", "modified learning convolution algorithm", "modified learning emotion algorithm"
"modified objective solution algorithmssss" » "modified objective evolution algorithmssss", "modified objective convolution algorithmsssss", "modified objective evolutionary algorithmssss", "modified objective allocation algorithmssss"

Try widening your search to All Fields.

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified learning solution algorithm") or ("modified objective solution algorithmssss"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified learning solution algorithm") OR ("modified objective solution algorithmssss")).
• Removing quotes may allow a broader search: (( modified learning solution algorithm ) or ( modified objective solution algorithmssss )).
• Adding a wildcard symbol may retrieve word variants: (("modified learning solution algorithm") or ("modified objective solution algorithmssss"))*.
