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

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