Perhaps you should try some spelling variations:
"modified objective optimisation algorithm" » "modified objective optimization algorithm", "modified multiobjective optimization algorithm", "modified objective optimization algorithms", "modified objective estimation algorithm", "modified objective 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.

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