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

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 location optimisation algorithm") OR ("modified allocation approximation algorithms"))~.
• Removing quotes may allow a broader search: (( modified location optimisation algorithm ) or ( modified allocation approximation algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified location optimisation algorithm") or ("modified allocation approximation algorithms"))*.
