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.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified adaptive evolution algorithm\") OR (\"modified invasive convolution algorithms\"))~".
• Removing quotes may allow a broader search: (( modified adaptive evolution algorithm ) OR ( modified invasive convolution algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified adaptive evolution algorithm") OR ("modified invasive convolution algorithms"))*.
