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"
"machines using low algorithm" » "machinery using low algorithm", "machines using mom algorithm", "machines using _ algorithm", "machines using our algorithm"

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

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