Perhaps you should try some spelling variations:
"machines learning convolution algorithm" » "machines learning convolution algorithms", "machines learning evolution algorithm", "machines learning solution algorithm", "machine learning convolution algorithm", "active learning convolution algorithm", "mapping learning convolution algorithm"
"modified objective estimation algorithms" » "modified objective estimation algorithm", "modified objective optimization algorithms", "modified objective optimisation algorithm", "modified objective allocation algorithms"

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: (("machines learning convolution algorithm") OR ("modified objective estimation algorithms"))~.
• Removing quotes may allow a broader search: (( machines learning convolution algorithm ) or ( modified objective estimation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("machines learning convolution algorithm") or ("modified objective estimation algorithms"))*.
