Perhaps you should try some spelling variations:
convolution algorithmss » convolution algorithms, evolution algorithm
invasive convolution » invasive ventilation
solution algorithm » evolution algorithm, convolution algorithms, evolutionary algorithm
modified invasive » modified passive
modified adaptive » modified passive

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 invasive convolution algorithmss ) OR ( modified adaptive solution algorithm ))~".
• Adding a wildcard symbol may retrieve word variants: (( modified invasive convolution algorithmss ) OR ( modified adaptive solution algorithm ))*.
