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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"powder using method algorithm\") OR (\"modified multiobjective optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( powder using method algorithm ) OR ( modified multiobjective optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("powder using method algorithm") OR ("modified multiobjective optimization algorithms"))*.
