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

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