Perhaps you should try some spelling variations:
"modified multiobjective optimization algorithm" » "modified multiobjective optimization algorithms", "modified multiobjective optimisation algorithm", "modified multiobjective estimation algorithm"
"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 optimization algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machinery using real algorithm") OR ("modified multiobjective optimization algorithm")).
• Removing quotes may allow a broader search: (( machinery using real algorithm ) or ( modified multiobjective optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("machinery using real algorithm") or ("modified multiobjective optimization algorithm"))*.
