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 one algorithm" » "machines using one algorithm", "machinery using our algorithm", "machinery using _ algorithm", "machinery using mom algorithm", "machinery using open algorithm", "machinery using pre algorithm", "machinery using online algorithm"

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (("modified multiobjective optimisation algorithm") or ("machinery using one algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified multiobjective optimisation algorithm") OR ("machinery using one algorithm")).
• Removing quotes may allow a broader search: (( modified multiobjective optimisation algorithm ) or ( machinery using one algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified multiobjective optimisation algorithm") or ("machinery using one algorithm"))*.
