Perhaps you should try some spelling variations:
"modified multiobjective optimized algorithms" » "modified multiobjective optimization algorithms", "modified multiobjective optimized algorithm", "modified multiobjective optimizer algorithms"
"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 optimized algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("coarse grain method algorithm") OR ("modified multiobjective optimized algorithms")).
• Removing quotes may allow a broader search: (( coarse grain method algorithm ) or ( modified multiobjective optimized algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("coarse grain method algorithm") or ("modified multiobjective optimized algorithms"))*.
