Perhaps you should try some spelling variations:
"modified notion optimisation algorithm" » "modified notion optimization algorithms", "modified notion estimation algorithm", "modified network optimization algorithm"
"modified based estimation algorithms" » "modified based estimation algorithm", "modified based optimization algorithms", "modified based approximation algorithms", "modified pose estimation algorithms", "modified based investigation algorithms", "modified pulses estimation algorithms", "modified male 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 based estimation algorithms") OR ("modified notion optimisation algorithm"))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified based estimation algorithms\") OR (\"modified notion optimisation algorithm\"))*".
• Removing quotes may allow a broader search: (( modified based estimation algorithms ) OR ( modified notion optimisation algorithm ))*.
