Perhaps you should try some spelling variations:
"modified invasive convolution algorithms" » "modified invasive evolution algorithm", "modified invasive ventilation algorithms", "modified passive convolution algorithms"
"machine learning solution algorithm" » "machine learning evolution algorithm", "machine learning evolutionary algorithm", "machine learning estimation algorithm", "machine learning convolution algorithm", "machine 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: (("modified invasive convolution algorithms") or ("machine learning solution algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified invasive convolution algorithms") OR ("machine learning solution algorithm")).
• Removing quotes may allow a broader search: (( modified invasive convolution algorithms ) or ( machine learning solution algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified invasive convolution algorithms") or ("machine learning solution algorithm"))*.
