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