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"
"machinery using real algorithm" » "machines using real algorithm", "machinery using adam algorithm", "machinery using search algorithm", "machinery using metal algorithm", "machinery using raw 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: (("machinery using real algorithm") or ("modified multiobjective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machinery using real algorithm") OR ("modified multiobjective optimisation algorithm")).
• Removing quotes may allow a broader search: (( machinery using real algorithm ) or ( modified multiobjective optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machinery using real algorithm") or ("modified multiobjective optimisation algorithm"))*.
