Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified allocation optimisation algorithms", "modified allocation estimation algorithmss", "modified alstatic optimization algorithms"
"modified location optimization algorithm" » "modified location optimisation algorithm", "modified location estimation algorithm", "modified location estimation algorithms", "modified static optimization algorithm", "modified carbon optimization 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 location optimization algorithm\") OR (\"modified allocation optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( modified location optimization algorithm ) OR ( modified allocation optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified location optimization algorithm") OR ("modified allocation optimization algorithms"))*.
