Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"coarse learning emotion algorithm" » "coarse learning evolution algorithm", "coarse learning estimation algorithm", "coarse learning predation algorithm", "coarse learning method algorithm", "coarse graining emotion 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: (("coarse learning emotion algorithm") or ("modified multiobjective optimized algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("coarse learning emotion algorithm") OR ("modified multiobjective optimized algorithm")).
• Removing quotes may allow a broader search: (( coarse learning emotion algorithm ) or ( modified multiobjective optimized algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("coarse learning emotion algorithm") or ("modified multiobjective optimized algorithm"))*.
