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

You may be able to get more results by adjusting your search query.

• Performing a fuzzy search may retrieve terms with similar spellings: (( modified passive optimizer algorithms ) OR ( modified invasive convolution algorithms ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( modified passive optimizer algorithms ) OR ( modified invasive convolution algorithms ))".
• Adding a wildcard symbol may retrieve word variants: (( modified passive optimizer algorithms ) OR ( modified invasive convolution algorithms ))*.
