Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"coarse learning method algorithm" » "coarse learning mom algorithm", "coarse graining method algorithm", "coarse learning methods algorithm", "coarse graining methods algorithm", "coarse learning emotion algorithm"

You may be able to get more results by adjusting your search query.

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