Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"powder using source algorithm" » "powder using our algorithm", "powder using search algorithm", "code using source algorithm", "boiler using source algorithm", "model using source algorithm", "powder using force algorithm", "powder using morse 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 source algorithm\") OR (\"modified multiobjective optimization algorithm\"))~".
• Removing quotes may allow a broader search: (( powder using source algorithm ) OR ( modified multiobjective optimization algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("powder using source algorithm") OR ("modified multiobjective optimization algorithm"))*.
