Perhaps you should try some spelling variations:
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"
"machines learning methods algorithm" » "machine learning methods algorithm", "active learning methods algorithm", "mapping learning methods algorithm", "machines nursing 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: (("machines learning methods algorithm") or ("modified objective estimation algorithms"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("machines learning methods algorithm") OR ("modified objective estimation algorithms")).
• Removing quotes may allow a broader search: (( machines learning methods algorithm ) or ( modified objective estimation algorithms )).
• Adding a wildcard symbol may retrieve word variants: (("machines learning methods algorithm") or ("modified objective estimation algorithms"))*.
