Perhaps you should try some spelling variations:
"modified notion optimization algorithms" » "modified notion optimisation algorithm", "modified notion estimation algorithms", "modified notion estimation algorithm", "modified network optimization algorithms", "modified policy optimization algorithms", "modified allocation optimization algorithms"
"modified cover optimized algorithm" » "modified cover optimized algorithms", "modified cover optimizer algorithms", "modified covers optimized algorithm", "modified over optimized algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"modified notion optimization algorithms\") OR (\"modified cover optimized algorithm\"))~".
• Removing quotes may allow a broader search: (( modified notion optimization algorithms ) OR ( modified cover optimized algorithm ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified notion optimization algorithms") OR ("modified cover optimized algorithm"))*.
