Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithm" » "modified multiobjective optimization algorithm", "modified multiobjective optimized algorithms", "modified multiobjective optimizer algorithms"
"coarse graining methods algorithm" » "coarse learning methods algorithm", "coarse learning method algorithm", "coarse making methods algorithm", "coarse grain methods algorithm", "coarse grained methods 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 multiobjective optimized algorithm") or ("coarse graining methods algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimized algorithm") OR ("coarse graining methods algorithm"))*.
• Removing quotes may allow a broader search: (( modified multiobjective optimized algorithm ) or ( coarse graining methods algorithm ))*.
