Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"coarse grained method algorithm" » "coarse grained mom algorithm", "coarse grain method algorithm", "coarse graining method algorithm", "coarse graining methods 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 grained method algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• Removing quotes may allow a broader search: (( coarse grained method algorithm ) or ( modified multiobjective optimizer algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("coarse grained method algorithm") or ("modified multiobjective optimizer algorithms"))*.
