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