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