Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithms" » "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithms", "modified multiobjective estimation algorithm"
"powder using method algorithm" » "powder using mom algorithm", "code using method algorithm", "boiler using method algorithm", "model using method algorithm", "powder nursing methods algorithm", "powder focusing method algorithm", "powder using metal algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimization algorithms") or ("powder using method algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimization algorithms") OR ("powder using method algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimization algorithms ) or ( powder using method algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimization algorithms") or ("powder using method algorithm"))*.
