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 orca optimized algorithms" » "modified orca optimized algorithm", "modified orca optimizer algorithms", "modified orca optimization algorithms", "modified dorca optimized algorithms", "modified orcad optimized algorithms", "modified ohca 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 orca optimized algorithms") or ("modified notion optimisation algorithm"))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: (("modified orca optimized algorithms") OR ("modified notion optimisation algorithm")).
• Removing quotes may allow a broader search: (( modified orca optimized algorithms ) or ( modified notion optimisation algorithm )).
• Adding a wildcard symbol may retrieve word variants: (("modified orca optimized algorithms") or ("modified notion optimisation algorithm"))*.
