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"
"model using method algorithm" » "model using mom algorithm", "model nursing methods algorithm", "model focusing method algorithm", "model using metal algorithm", "code using method algorithm", "models nursing method algorithm", "powder using method 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: (("model using method algorithm") OR ("modified allocation optimization algorithms"))~.
• Removing quotes may allow a broader search: (( model using method algorithm ) or ( modified allocation optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("model using method algorithm") or ("modified allocation optimization algorithms"))*.
