Perhaps you should try some spelling variations:
"modified objective solution algorithms" » "modified objective evolution algorithm", "modified objective convolution algorithms", "modified objective estimation algorithms", "modified objective evolution algorithms", "modified objective convolution algorithmss", "modified objective evolutionary algorithms", "modified objective allocation algorithms"
"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"

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