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