Perhaps you should try some spelling variations:
"modified allocation optimization algorithms" » "modified allocation optimisation algorithm", "modified allocation estimation algorithms", "modified allocation estimation algorithm", "modified location optimization algorithms"
"modified caging estimation algorithmss" » "modified caging estimation algorithms", "modified caging estimation algorithm", "modified lighting estimation algorithmss"

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 allocation optimization algorithms\") OR (\"modified caging estimation algorithmss\"))~".
• Removing quotes may allow a broader search: (( modified allocation optimization algorithms ) OR ( modified caging estimation algorithmss ))~.
• Adding a wildcard symbol may retrieve word variants: (("modified allocation optimization algorithms") OR ("modified caging estimation algorithmss"))*.
