Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"effective graining methods algorithm" » "effective gradient methods algorithm", "effective reading methods algorithm", "effective learning methods algorithm", "effective learning method algorithm", "effective making 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: (("effective graining methods algorithm") or ("modified multiobjective optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("effective graining methods algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( effective graining methods algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("effective graining methods algorithm") or ("modified multiobjective optimization algorithm"))*.
