Perhaps you should try some spelling variations:
"modified multiobjective estimation algorithm" » "modified multiobjective optimization algorithm"
"enabling learning convolution algorithm" » "enabling learning convolution algorithms", "enabling learning evolution algorithm", "enabling learning solution algorithm", "mapping learning convolution algorithm"

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