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"
"powder learning method algorithm" » "powder learning mom algorithm", "powder learning methods algorithm", "powder graining methods algorithm", "powder learning emotion algorithm", "power learning method 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: (("powder learning method algorithm") OR ("modified multiobjective optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( powder learning method algorithm ) or ( modified multiobjective optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("powder learning method algorithm") or ("modified multiobjective optimisation algorithm"))*.
