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