Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"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.

• Performing a fuzzy search may retrieve terms with similar spellings: (("coarse grained method algorithm") OR ("modified multiobjective optimized algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coarse grained method algorithm\") OR (\"modified multiobjective optimized algorithms\"))".
• Removing quotes may allow a broader search: (( coarse grained method algorithm ) OR ( modified multiobjective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("coarse grained method algorithm") OR ("modified multiobjective optimized algorithms"))*.
