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"
"machine graining methods algorithm" » "machine learning methods algorithm", "machine learning method algorithm", "machine making methods algorithm"

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

• Performing a fuzzy search may retrieve terms with similar spellings: (("machine graining methods algorithm") or ("modified objective optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machine graining methods algorithm") OR ("modified objective optimisation algorithm"))*.
• Removing quotes may allow a broader search: (( machine graining methods algorithm ) or ( modified objective optimisation algorithm ))*.
