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