Perhaps you should try some spelling variations:
"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"
"modified invasive approximation algorithms" » "modified passive approximation algorithms"

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 approximation algorithms") OR ("modified static optimization algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified invasive approximation algorithms\") OR (\"modified static optimization algorithm\"))*".
• Removing quotes may allow a broader search: (( modified invasive approximation algorithms ) OR ( modified static optimization algorithm ))*.
