Perhaps you should try some spelling variations:
"modified multiobjective optimisation algorithm" » "modified multiobjective optimization algorithm", "modified objective optimization algorithm", "modified multiobjective optimization algorithms", "modified multiobjective estimation algorithm", "modified multiobjective estimation algorithms"
"powder using search algorithm" » "powder using source algorithm", "code using search algorithm", "boiler using search algorithm", "model using search algorithm", "powder using egarch algorithm", "powder nursing research algorithm", "powder using servo algorithm"

Try widening your search to All Fields.

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

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