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