Perhaps you should try some spelling variations:
"modified location optimisation algorithm" » "modified location optimization algorithms", "modified location estimation algorithm", "modified location estimation algorithms", "modified allocation optimization algorithm", "modified carbon optimisation algorithm"
"modified notion optimized algorithms" » "modified notion optimized algorithm", "modified notion optimizer algorithms", "modified notion optimization algorithms"

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

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