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 pre algorithm" » "powder using mppt algorithm", "powder using qspr algorithm", "powder using _ algorithm", "code using pre algorithm", "boiler using pre algorithm", "model using pre algorithm", "powder nursing pre algorithm", "powder using one algorithm", "powder using ph 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 pre algorithm") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("powder using pre algorithm") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( powder using pre algorithm ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("powder using pre algorithm") or ("modified multiobjective optimisation algorithm"))*.
