Perhaps you should try some spelling variations:
"machine learning convolution algorithms" » "machine learning evolution algorithm", "machine learning solution algorithm"
"modified parameter optimisation algorithm" » "modified parameter optimization algorithm", "modified parameter estimation algorithm", "modified parameter optimization algorithms", "modified parameter estimation 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: (("machine learning convolution algorithms") OR ("modified parameter optimisation algorithm"))~.
• Removing quotes may allow a broader search: (( machine learning convolution algorithms ) or ( modified parameter optimisation algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("machine learning convolution algorithms") or ("modified parameter optimisation algorithm"))*.
