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"
"machines learning method algorithm" » "machine learning method algorithm", "active learning method algorithm", "mapping learning method algorithm", "machines learning mom algorithm", "machines learning methods algorithm", "machines graining methods algorithm", "machines learning emotion algorithm"

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

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