Perhaps you should try some spelling variations:
"modified multiobjective optimizer algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithms", "modified multiobjective optimized algorithm"
"coarse grain method algorithm" » "coarse grain mom algorithm", "coarse grain motion algorithm", "coarse graining methods algorithm", "coarse group method algorithm", "course grain method 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 grain method algorithm") OR ("modified multiobjective optimizer algorithms"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"coarse grain method algorithm\") OR (\"modified multiobjective optimizer algorithms\"))".
• Removing quotes may allow a broader search: (( coarse grain method algorithm ) OR ( modified multiobjective optimizer algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("coarse grain method algorithm") OR ("modified multiobjective optimizer algorithms"))*.
