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 force algorithm" » "powder using source algorithm", "powder using search algorithm", "code using force algorithm", "boiler using force algorithm", "model using force algorithm", "powder using morse algorithm", "powder cutting force 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 force algorithm") or ("modified multiobjective optimization algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("powder using force algorithm") OR ("modified multiobjective optimization algorithms")).
• Removing quotes may allow a broader search: (( powder using force algorithm ) or ( modified multiobjective optimization algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("powder using force algorithm") or ("modified multiobjective optimization algorithms"))*.
