Perhaps you should try some spelling variations:
"modified passive convolution algorithms" » "modified passive evolution algorithm", "modified passive solution algorithm", "modified adaptive convolution algorithms"
"modified static optimization algorithm" » "modified static optimization algorithms", "modified static optimisation algorithm", "modified static estimation algorithm", "modified stage optimization algorithm", "modified stochastic optimization algorithm", "modified staffing optimization 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 passive convolution algorithms") OR ("modified static optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified passive convolution algorithms\") OR (\"modified static optimization algorithm\"))".
• Removing quotes may allow a broader search: (( modified passive convolution algorithms ) OR ( modified static optimization algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified passive convolution algorithms") OR ("modified static optimization algorithm"))*.
