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