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